The full-scale output current is set with two external sense resistors. The output compliance voltage is 2.5 V, even at output currents up to 300 mA.The device is particularly suited for tunable laser control and can drive tunable laser front mirror, back mirror, phase, gain, and amplification sections. A host CPU or microcontroller controls the operation of the ADN8810 over a 3-wire serial peripheral interface (SPI). The 3-bit address allows up to eight devices to be independently controlled while attached to the same SPI bus.The ADN8810 is guaranteed with ±4 LSB integral nonlinearity (INL) and ±0.75 LSB differential nonlinearity (DNL). Noise and digital feedthrough are kept low to ensure low jitteroperation for laser diode applications.

C | Page 9 of 14TERMINOLOGYRelative AccuracyRelative accuracy or integral nonlinearity (INL) is a measure of the maximum deviation, in least significant bits (LSBs), from an ideal line passing through the endpoints of the DAC transfer function. Figure 4 shows a typical INL vs. code plot. The ADN8810 INL is measured from 2% to 100% of the full-scale (FS) output.Differential NonlinearityDifferential nonlinearity (DNL) is the difference between the measured change and the ideal 1 LSB change between any two adjacent codes. A specified differential nonlinearity of ± 1 LSB maximum ensures monotonicity. The ADN8810 is guaranteed monotonic by design. Figure 5 shows a typical DNL vs. code plot . Offset ErrorOffset error, or zero-code error, is an interpolation of the output voltage at code 0x000 as predicted by the line formed from the output voltages at code 0x040 (2% FS) and code 0xFFF (100% FS). Ideally, the offset error is 0 V . Offset error occurs from a combination of the offset voltage of the amplifier and offset errors in the DAC. It is expressed in LSBs.Offset DriftThis is a measure of the change in offset error with a change in temperature. It is expressed in (ppm of full-scale range)/°C. Gain ErrorGain error is a measure of the span error of the DAC. It is the deviation in slope of the output transfer characteristic from ideal. The transfer characteristic is the line formed from the output voltages at code 0x040 (2% FS) and code 0xFFF (100% FS). It is expressed as a percent of the full-scale range.Compliance VoltageThe maximum output voltage from the ADN8810 is a function of output current and supply voltage. Compliance voltage defines the maximum output voltage at a given current and supply voltage to guarantee the device operates within its INL, DNL, and gain error specifications.Output Current Change vs. Output Voltage ChangeThis is a measure of the ADN8810 output impedance and is similar to a load regulation spec in voltage references. For a given code, the output current changes slightly as output voltage increases. It is measured as an absolute value in (ppm of full-scale range)/V .O U T P U T V O L T A G E03195-0-004Figure 16. Output Transfer FunctionADN8810Data SheetRev. C | Page 10 of 14FUNCTIONAL DESCRIPTIONThe ADN8810 is a single 12-bit current output digital-to-analog converter (DAC) with a 3-wire SPI interface. Up to eight devices can be independently programmed from the same SPI bus. The full-scale output current is set with two external resistors. The maximum output current can reach 300 mA. Figure 17 shows the functional block diagram of the ADN8810.03195-0-017Figure 17. Functional Blocks, Pins, and Internal ConnectionsSETTING FULL-SCALE OUTPUT CURRENTTwo external resistors set the full-scale output current from the ADN8810. These resistors are equal in value and are labeled R SN in Figure 1. Use 1% or better tolerance resistors to achieve the most accurate output current and the highest output impedance.Equation 3 shows the approximate full-scale output current. The exact output current is determined by the data register code as shown in Equation 4. The variable code is an integer from 0 to 4095, representing the full 12-bit range of the ADN8810.SNFS R I ×≈10096.4(3)+Ω××=1.0151000,1k R R Code I SN SN OUT(4)The ADN8810 is designed to operate with a 4.096 V referencevoltage connected to VREF. The output current is directly proportional to this reference voltage. To achieve the bestperformance, use a low noise precision (the ADR292, ADR392, or REF198 is recommended).POWER SUPPLIESThere are three principal supply current paths through the ADN8810: •AVDD provides power to the analog front end of the ADN8810 including the DAC. Use this supply line topower the external voltage reference. For best performance, AVDD must be low noise.•DVDD provides power for the digital circuitry. Thisincludes the serial interface logic, the SB and RESET logic inputs, and the FAULT output. Tie DVDD to the same supply line used for other digital circuitry. It is not necessary for DVDD to be low noise.•PVDD is the power pin for the output amplifier. It canoperate from as low as 3.0 V to minimize power dissipation in the ADN8810. For best performance, PVDD must be low noise.Current is returned through the following three pins: •AVSS is the return path for both AVDD and PVDD. This pin is connected to the substrate of the die as well as the slug on the bottom of the lead frame chip scale package (LFCSP). For single-supply operation, connect this pin to a low noise ground plane.•DVSS returns current from the digital circuitry powered by DVDD. Connect DVSS to the same ground line or plane used for other digital devices in the application.•DGND is the ground reference for the digital circuitry. In a single-supply application, connect DGND to DVSS.For single-supply operation, set AVDD to 5 V , set PVDD from 3.0 V to 5 V , and connect AVSS, AGND, and DGND to ground.SERIAL DATA INTERFACEThe ADN8810 uses a serial peripheral interface (SPI) with three input signals: SDI, CLK, and CS . Figure 2 shows the timing diagram for these signals.Data applied to the SDI pin is clocked into the input shift register on the rising edge of CLK. After all 16 bits of the data-word have been clocked into the input shift register, a logic high on CS loads the shift register byte into the ADN8810. If more than 16 bits of data are clocked into the shift register before CS goes high, bits are pushed out of the register in first-in first-out (FIFO) fashion.The four MSB of the data byte are checked against the address of the device. If they match, the next 12 bits of the data byte are loaded into the DAC to set the output current. The first bit (MSB) of the data byte must be a logic zero, and the following three bits must correspond to the logic levels on pins ADDR2, ADDR1, and ADDR0, respectively, for the DAC to be updated. Up to eight ADN8810 devices with unique addresses can be driven from the same serial data bus.Table 5 shows how the 16-bit DATA input word is divided into an address byte and a data byte. The first four bits in the input word correspond to the address. Note that the first bit loaded (A3) must always be zero. The remaining bits set the 12-bit data byte for the DAC output. Three example inputs are demonstrated.•Example 1: This SDI input sets the device with an address of 111 to its minimum output current, 0 A. Connecting the ADN8810 pins ADDR2, ADDR1, and ADDR0 to VDD sets this address.• Example 2: This input sets the device with an address of 000 to a current equal to half of the full-scale output. •Example 3: The ADN8810 with an address of 100 is set to full-scale output.STANDBY AND RESET MODESApplying a logic low to the SB pin deactivates the ADN8810 and puts the output into a high impedance state. The device continues to draw 1.3 mA of typical supply current in standby. When logic high is reasserted on the SB pin, the output current returns to its previous value within 6 µs.Applying logic low to RESET sets the ADN8810 data register to all zeros, bringing the output current to 0 A. When RESET is deasserted, the data register can be reloaded. Data cannot be loaded into the device while it is in standby or reset mode.POWER DISSIPATIONThe power dissipation of the ADN8810 is equal to the output current multiplied by the voltage drop from PVDD to the output.()SN OUT OUT OUT DISS R I V PVDD I P ×−−×=²(5)The power dissipated by the ADN8810 causes a temperature increase in the device. For this reason, PVDD must be as low as possible to minimize power dissipation.While in operation, the ADN8810 die temperature, also known as junction temperature, must remain below 150°C to prevent damage. The junction temperature is approximatelyDISS JA A J P T T ×θ+=(6)where:T A is the ambient temperature in °C,θJA is the thermal resistance of the package (32°C/W). •Example 4: A 300 mA full-scale output current is required to drive a laser diode within an 85°C environment. The laser diode has a 2 V drop and PVDD is 3.3 V .Using Equation 5, the power dissipation in the ADN8810 is found to be 267 mW . At T A = 85°C, this makes the junction temperature 93.5°C, which is well below the 150°C limit. Note that even with PVDD set to 5 V , the junction temperature increases to only 110°C.USING MULTIPLE ADN8810 DEVICES FOR ADDITIONAL OUTPUT CURRENTConnect multiple ADN8810 devices in parallel to increase the available output current. Each device can deliver up to 300 mA of current. To program all parallel devices simultaneously, set all device addresses to the same address byte and drive all CS , SDI, and CLK from the same serial data interface bus. The circuit in Figure 18 uses two ADN8810 devices and delivers 600 mA to the pump laser.SERIAL INTERFACE (FROM µC OR DSP)I 600mA03195-0-018Figure 18.

This is accomplished by dithering the V REF voltage input to the ADN8810. Figure 19 demonstrates one method.DITHERR203195-0-019Figure 19. Adding Dither to the Reference VoltageSet the gain of the dither by adjusting the ratio of R2 to R1. Increase C to lower the cutoff frequency of the high-pass filter created by C and R1. The cutoff frequency of Figure 19 is approximately 98 Hz.The AD8605 is recommended as a low offset, rail-to-rail input amplifier for this circuit.DRIVING COMMON-ANODE LASER DIODESThe ADN8810 can power common-anode laser diodes. These are laser diodes whose anodes are fixed to the laser module case. The module case is typically tied to either VDD or ground. For common anode to ground applications, a −5 V supply must be provided.In Figure 20, R SN sets up the diode current by the following equation:40965.16111.1096.4Code k R I SN ×Ω+×=(7)where Code is an integer value from 0 to 4095.Using the values in Figure 20, the diode current is 300.7 mA at a code value of 2045 (0x7FF), or half full-scale. This effectively provides 11-bit current control from 0 mA to 300 mA of diode current.The maximum output current of this configuration is limited by the compliance voltage at the IOUT pin of the ADN8810. The voltage at IOUT cannot exceed 1 V below PVDD, in this case, 4 V. The IOUT voltage is equal to the voltage drop across R S N plus the gate-to-source voltage of the external FET. For this reason, select a FET with a low threshold voltage.In addition, the voltage across the R SN resistor cannot exceed the voltage at the cathode of the laser diode. Given a forward laser diode voltage drop of 2 V in Figure 20, the voltage at the RSN pin (I × R SN ) cannot exceed 3 V . This sets an upper limit to the value of code in Equation 5.Although the configuration for anode-to-ground diodes is similar, the supply voltages must be shifted down to 0 V and −5 V , as shown in Figure 21. The AVDD, DVDD, and PVDD pins are connected to ground with AVSS connected to −5 V .The 4.096 V reference must also be referred to the −5 V supply voltage. The diode current is still determined by Equation 7. All logic levels must be shifted down to 0 V and −5 V levels as well. This includes RESET , CS , SCLK, SDI, SB , and all ADDR pins. Figure 22 shows a simple method to level shift a standard TTL or CMOS (0 V to 5 V) signal down using external FETs.NOTE: LEAVE FB WITH NO CONNECTION03195-0-020Figure 20.

Level Shifting TTL/CMOS LogicPCB LAYOUT RECOMMENDATIONSAlthough they can be driven from the same power supply voltage, keep DVDD and AVDD current paths separate on the printed circuit board (PCB) to maintain the highest accuracy; likewise for AVSS and DGND. Tie common potentials together at a single point located near the power regulator. This technique is known as star grounding and is shown in Figure 23. This method reduces digital crosstalk into the laser diode or load.LOGIC GROUNDRETURN03195-0-023Figure 23. Star Supply and Ground TechniqueTo improve thermal dissipation, solder the slug on the bottom of the LFCSP package be soldered to the PCB with multiple vias into a low noise ground plane. Connecting these vias to a copper area on the bottom side of the board further improves thermal dissipation.Use identical trace width and lengths for the two output sense resistors. These lengths are shown as X and Y in Figure 24. Differences in trace lengths cause differences in parasitic seriesresistance. Because the sense resistors can be as low as 1.37 Ω, small parasitic differences can lower both the output current accuracy and the output impedance. See the AN-619 Application Note for a sample layout for these traces.03195-0-024Figure 24. Use Identical Trace Lengths for Sense ResistorsSUGGESTED PAD LAYOUT FOR CP-24 PACKAGEFigure 25 shows the dimensions for the PCB pad layout for the ADN8810. The package is a 4 mm × 4 mm, 24-lead LFCSP . The metallic slug underneath the package must be soldered to a copper pad connected to AVSS, the lowest supply voltage to the ADN8810. For single-supply applications, this is ground.

These tools arecomprised of:• Energy meter reference design• 1-pin emulator with isolated USB interface• Isolated USB to UART debugger interface• Downloader software• Evaluation software• Integrated development environment from well-known vendor• Firmware libraries for common and part specific functionsThe energy meter reference design integrates the main functions of an LCD meter withIR port and RS-485 communication, battery backup, two current sensors, antitamperinterface, and EEPROM interface while using the features of the ADE71xx and ADE75xxseries such as battery management, antitamper detection, temperature compensatedreal-time clock, and LCD driver contrast.The reference design is accompanied by code libraries and an example of systemintegration code allowing easy evaluation and further development of solution.Isolated USB communication boards for debugging and emulation provide a safesolution for code development when the meter is connected to the line.The ADE71xx and ADE75xx series can be used with integrated developmentenvironments (IDE) from open market vendors to simulate, compile, debug, anddownload assembly or C code. A free of charge IDE with unlimited assembly codecapability and 4 kB limited C code capability is included in the evaluation kit. Inaddition, the part can be evaluated with a UART interface and a PC by using theversatile evaluation tools and downloader.Single-Phase Energy Metering ICs with Integrated OscillatorThe AD71056, ADE7768, and ADE7769 are single-phase ICs that provide watt-hour information using pulse outputs that directly drive a stepper motor counter.The AD71056, ADE7768, and ADE7769 are pin-reduced versions of the ADE7755, with the enhancement of an on-chip, precisionoscillator circuit that serves as the clock source for the IC. The direct interface to low resistance, low cost shunt resistors also helps to lower the cost of a meter built with AD71056, ADE7768, or ADE7769.These products are pin compatible. The AD71056 and ADE7769 accumulate bidirectional power information, and the ADE7768accumulates power only in the positive direction providing flexibility for various billing schemes. The ADE7769 indicates when the power is below the no-load threshold by holding the calibration frequencypin high. This is useful to indicate a tampering or miswired condition.Single-Phase Energy Metering ICs with Antitamper FeaturesThe ADE7761B detects two common tampering conditions: “fault” condition (when loads are grounded to earth instead of connected to neutral wire or when the meter is bypassed with external wires) and “missing neutral” condition (when the voltage input and return current are missing). The ADE7761B incorporates a novel tampering detection scheme which indicates the fault or missing neutral conditions and allows the meter to continue accurate billing by continuous monitoring of the phase and neutral (return) currents. A fault is indicated when these currents differ by more than 6.25%, and billing continues using the larger of the two currents. The missing neutral condition is detected when no voltage input is present, and billing is continued based on the active current signal. The ADE7761B also includes a power-supply monitoring circuit which ensures that the voltage and current channels are matched,eliminating creep effects in the meter.Polyphase Energy Metering ICs with Pulse OutputThe ADE7752A, ADE7752B, and ADE7762 are polyphase ICs that provide watt-hour information using pulse outputs that can directly drive a stepper motor counter. Compatible with a wide range of 3-phase grid configurations, including 3-wire and 4-wire delta and wye distributions, each of these products can be used for 3-phase commercial and industrial revenue meters or submeters, 3-phase motors or generators, industrial control, and utility automation. The ADE7762 and ADE7752B are optimized for 3-phase, 3-wire applica-tions with no-load threshold and REVP indication based on the sum of the phases.To ensure that energy is billed properly under miswiring or tamper-ing conditions, any of the ICs can be set to accumulate based on the sum of the absolute value in each phase. The active power accumu-lation is signed by default.The ADE7762 has four additional logic output pins. These four pins drive six LEDs for prioritized indication of phase dropout and phasesequence error as well as reverse polarity per phase.ADE7752A and ADE7752B are pin compatible with the legacy ADE7752 and have up to a 50% power consumption reduction from ADE7752. The four additional pins of ADE7762 are located at the top of the package so that the same PCB may be used with an ADE7752A-, ADE7752B-, or ADE7762-based meter.10Single-Phase Energy Metering ICs with Serial InterfaceADI has a range of product offerings for single-phase energy measurement solutions requiring serial interface. The ADE7756 measures active energy and allows digital calibration of phase, offset, and gain through a serial port interface. The ADE7759 has a built-in digital integrator for direct interface with a di/dt sensor such as a Rogowski coil and includes the capability to interface with low resistance shunts and traditional current transformers. The ADE7753 provides active, apparent, and reactive energy measurements, and incorporates a built-in digital integrator to allow direct interface with a Rogowski coil sensor in addition to a low resistance shunt or CT. The ADE7763 provides the same functionality as the ADE7753 but without reactive energy measurement. All four of these ADE single-phase energy metering ICs with SPI are pin compatible for ease of design migration.11Polyphase Energy Metering ICs with Serial InterfaceADI has a selection of product offerings for3-phase energy measurement solutions requiring serial interface. The ADE7758 features second-order sigma-delta ADCs, and is designed formidrange 3-phase energy meters. For each phase, the chip measures active, reactive, and apparent energy, as well as rms voltage and rms current. These measurements are accessed via an SPI that allows a fully automated digital calibration. The ADE7758 interfaces with a variety of sensors, including current transformers and di/dt current sensors, such as Rogowski coils. Additionally, the ADE7758 provides a programmable frequency pulse output for both active and apparent orreactive power.Analog Devices, Inc.Worldwide Headquarters Analog Devices, Inc.

Be careful to observe the correct polarity. On-board regulators provide 5V to the LTC1298’s V CC pin. LT1121-5 and LT1021 regulators generate 5V for the digital circuitry and ADC, respectively.Applying the Analog InputAnalog input signals are applied to the LTC1298’s two-channel (CH0 and CH1) input multiplexer through the demonstration board’s turret terminals E3 (CH0) and E4 (CH1). The input signals’ ground reference is applied to turret terminal E5. The analog signal input range is 0V to 5V. Optimum performance is achieved using a signal source that has low output impedance, is low noise, and34DEMO MANUAL DC045OPERATIOUhas low distortion. Signal generators such as the B & K Type 1051 sine generator give excellent results.Applying the Clock SignalThe clock signal is applied to BNC connector J1 and the CS signal is generated on the board. The clock input uses TTL or CMOS levels. The maximum clock frequency is 200kHz. While the clock signal is active, a high-to-low logic level transition is generated on the LTC1298’s CS input which initiates a conversion. The data transfer is shown in the timing diagrams (Figure 1).Reading the Output DataThe LTC1298 serial data outputs are buffered by the two 74HC595 latches and are available as a parallel output on connector JP3. The latches are used to drive the LEDs D0to D11. (Refer to the LTC1298 data sheet for details on different digital interface modes.)The LTC1298 output data is in unipolar format. A Data Ready line, RDY, (JP3 pin 13) is provided to latch the data.Data is valid on the rising edge of RDY. Connector JP3 has one ground pin (JP3 pin 14). Connect this pin to the data receiving system’s digital ground.MSB-First Data (MSBF = 0)Figure 1.

If open, the D IN line can be driven externally to configure the input multiplexer.The LTC1298’s data word can be acquired with a logic analyzer. By using a logic analyzer that has a PC-compat-ible floppy drive, (such as an HP1663A), conversion data can be stored on a disk and easily transferred to a PC. Once the data is transfered to a PC, programs such as Mathcad or Excel can be used to calculate FFTs. The FFTs can be used to obtain LTC1298 AC specifications such as signal-to-noise ratio and total harmonic distortion.LEDs D0 to D11 provide a visual display of the LTC1298’s digital output word. D0 is the LSB and D11 is the MSB.Jumper JP1 can be removed to disable the LEDs, reducing supply consumption by up to 56mA.Driving CS, D IN , and CLKJumpers for CS, CLK, D IN , and D OUT (JP2) are shorted for normal operation. The jumpers can be removed and CS,D IN , and CLK lines can be externally driven if desired. See the LTC1298 data sheet for details on driving these YOUTThe use of separate analog and digital ground planes is a good practice for a well designed LTC1298 PC board. Theproper way to make the analog and digital ground planes can be seen by examining the solder side of the PCB layout. The two ground planes are completely isolated except for one connection at the power supply ground input, E1. The two ground planes follow the same path on the component and solder sides of the board to reduce coupling between the ground planes. Also ensure that the analog ground plane’s solder side has a limited number of plane-breaking traces within it. Any trace that opens a portion of the ground plane may reduce the ground plane’s efficiency. Further, the analog and digital traces do not cross each other (whether on the board’s top or bottom side) or run adjacent to each other.BYPASSINGIt is important to place the supply/reference bypass ca-pacitor as close as possible to the LTC1298’s supply/reference pin. The ground side of the capacitor should have a very short path to analog ground. The V CC /V REF pins should be bypassed with high quality ceramic capaci-tors of at least 0.1µF.6DEMO MANUAL DC045OPERATIOUTable 2.INPUT/OUTPUT PINFUNCTIONJ1Clock InputE1GroundE27V to 15V at ≥100mA CH0Multiplexer Input Channel 0CH1Mulitplexer Input Channel 1AGND Input signals’ ground reference JP3-1D0 (LSB)JP3-2D1JP3-3D2JP3-4D3JP3-5D4JP3-6D5INPUT/OUTPUT PINFUNCTIONJP3-7D6JP3-8D7JP3-9D8JP3-10D9JP3-11D10JP3-12D11 (MSB)JP3-13RDY.
