Dual Universal Switched-Capacitor Filters
General Description
The MAX7490/MAX7491 consist of two identical lowpower, low-voltage, wide dynamic range, Rail-to-Rail®, 2nd-order switched-capacitor building blocks. Each of the two filter sections, together with two to four external resistors, can generate all standard 2nd-order functions: bandpass, lowpass, highpass, and notch (band reject). Three of these functions are simultaneously available. Fourth-order filters can be obtained by cascading the two 2nd-order filter sections. Similarly, higher order filters can easily be created by cascading multiple MAX7490/MAX7491s. Two clocking options are available: self-clocking (through the use of an external capacitor) or external clocking for tighter cutoff frequency control. The clockto-center frequency ratio is 100:1. Sampling is done at twice the clock frequency, further separating the cutoff frequency and Nyquist frequency. The MAX7490/MAX7491 have an internal rail splitter that establishes a precise common voltage needed for single-supply operation. The MAX7490 operates from a single +5V supply and the MAX7491 operates from a single +3V supply. Both devices feature a low-power shutdown mode and come in a 16-pin QSOP package.

MAX2605-MAX2609中文资料

General DescriptionThe MAX2605–MAX2609 evaluation kits (EV kits) simplify evaluation of this family of voltage-controlled oscillators (VCOs). These kits enable testing of the devices’ per-formance and require no additional support circuitry.Both signal outputs use SMA connectors to facilitate connection to RF test equipment.These EV kits are fully assembled and tested. Their oscil-lation frequencies are set to approximately the midrange of the respective VCOs.Featureso Easy Evaluationo Complete, Tunable VCO Test Board with Tank Circuit o Low Phase Noiseo Fully Assembled and TestedEvaluate: MAX2605–MAX2609MAX2605–MAX2609 Evaluation Kits19-1673 Rev 0; 9/00Ordering InformationComponent SuppliersFor free samples and the latest literature, visit or phone 1-800-998-8800.For small orders, phone 1-800-835-8769.MAX2606 Component ListMAX2605 Component ListE v a l u a t e : M A X 2605–M A X 2609MAX2605–MAX2609 Evaluation Kits 2_______________________________________________________________________________________Quick StartThe MAX2605–MAX2609 evaluation kits are fully assembled and factory tested. Follow the instructions in the Connections a nd Setup section for proper device evaluation.Test Equipment Required•Low-noise power supplies (these are recommended for oscillator noise measurement). Noise or ripple will frequency-modulate the oscillator and cause spectral spreading. Batteries can be used in place of power supplies, if necessary.– Use a DC power supply capable of supplying +2.7V to +5.5V. Alternatively, use two or three 1.5V batteries.– Use a DC power supply capable of supplying +0.4V to +2.4V, continuously variable, for TUNE.Alternatively, use two 1.5V batteries with a resistive voltage divider or potentiometer.•An RF spectrum analyzer that covers the operating frequency range of the MAX2605–MAX2609• A 50Ωcoaxial cable with SMA connectors •An ammeter (optional)Connections and Setup1)Connect a DC supply (preset to +3V) to the V CC and GND terminals (through an ammeter, if desired) on the EV kit.2)Turn on the DC supply.

Generally, the VCC pin on the PC board should have a decoupling capacitor placed close to the IC. This minimizes noisecoupling from the supply. Also, place the VCO as far away as possible from the noisy section of a larger sys-tem, such as a switching regulator or digital circuits.The VCO ’s performance is strongly dependent on the availability of the external tuning inductor. For best per-formance, use high-Q components and choose their val-ues carefully. To minimize the effects of parasitic ele-ments, which degrade circuit performance, place the tuning inductor and C BYP close to the VCO. For higher-frequency versions, include the parasitic PC board inductance and capacitance when calculating the oscillation frequency. In addition, remove the ground plane around and under the tuning inductor to minimize the effect of parasitic capacitance.Noise on TUNE translates into FM noise on the outputs;therefore, keep the trace between TUNE and the control circuitry as short as possible. If necessary, use an RC filter to further suppress noise, as done on the EV kits.E v a l u a t e : M A X 2605–M A X 2609MAX2605–MAX2609 Evaluation Kits 4_______________________________________________________________________________________Figure 2.

MAX8510 MAX8511 MAX8512 极低噪声、低掉电的线性调压器说明说明书

General DescriptionThe MAX8510/MAX8511/MAX8512 ultra-low-noise, low-dropout (LDO) linear regulators are designed to deliver up to 120mA continuous output current. These regulators achieve a low 120mV dropout for 120mA load current. The MAX8510 uses an advanced architecture to achieve ultra-low output voltage noise of 11μV RMS and PSRR of 54dB at 100kHz.The MAX8511 does not require a bypass capacitor, hence achieving the smallest PC board area. The MAX8512’s output voltage can be adjusted with an external divider.The MAX8510/MAX8511 are preset to a variety of voltag-es in the 1.5V to 4.5V range. Designed with a P-channel MOSFET series pass transistor, the MAX8510/MAX8511/MAX8512 maintain very low ground current (40μA).The regulators are designed and optimized to work with low-value, low-cost ceramic capacitors. The MAX8510 requires only 1μF (typ) of output capacitance for stability with any load. When disabled, current consumption drops to below 1μA.Package options include a 5-pin SC70 and a tiny 2mm x 2mm x 0.8mm TDFN package.Applications●Cellular and Cordless Phones ●PDA and Palmtop Computers ●Base Stations●Bluetooth Portable Radios and Accessories ●Wireless LANs ●Digital Cameras ●Personal Stereos●Portable and Battery-Powered EquipmentFeatures●Space-Saving SC70 and TDFN (2mm x 2mm) Packages ●11μV RMS Output Noise at 100Hz to 100kHzBandwidth (MAX8510)●78dB PSRR at 1kHz (MAX8510) ●120mV Dropout at 120mA Load●Stable with 1μF Ceramic Capacitor for Any Load ●Guaranteed 120mA Output●Only Need Input and Output Capacitors (MAX8511) ●Output Voltages: 1.5V, 1.8V, 2.5V, 2.6V, 2.7V, 2.8V,2.85V, 3V,3.3V,4.5V (MAX8510/MAX8511) and Adjustable (MAX8512) ●Low 40μA Ground Current ●Excellent Load/Line Transient●Overcurrent and Thermal Protection19-2732; Rev 5; 5/19Output Voltage Selector Guide appears at end of data sheet.Ordering Information continued at end of data sheet.*xy is the output voltage code (see Output Voltage Selector Guide).

The parts are available with preset output voltages ranging from 1.5V to 4.5V in 100mV increments. These devices can supply loads up to 120mA. As shown in the Functional Diagram , the MAX8510/MAX8511 consist of an innovative bandgap core and noise bypass circuit, error amplifier, P-channel pass transistor, and internal feedback voltage-divider. The MAX8512 allows for adjustable output with an external feedback network.The 1.225V bandgap reference is connected to the error amplifier’s inverting input. The error amplifier compares this reference with the feedback voltage and amplifies the difference. If the feedback voltage is lower than the refer-ence voltage, the pass-transistor gate is pulled low. This allows more current to pass to the output and increases the output voltage. If the feedback voltage is too high, the pass transistor gate is pulled high, allowing less cur-rent to pass to the output. The output voltage is fed back through an internal resistor voltage-divider connected to the OUT pin.An external bypass capacitor connected to BP (MAX8510) reduces noise at the output. Additional blocks include a current limiter, thermal sensor, and shutdown logic.Internal P-Channel Pass TransistorThe MAX8510/MAX8511/MAX8512 feature a 1Ω (typ) P-channel MOSFET pass transistor. This provides sev-eral advantages over similar designs using a PNP pass transistor, including longer battery life. The P-channel MOSFET requires no base drive, which considerably reduces quiescent current. PNP-based regulators waste considerable current in dropout when the pass transistor saturates. They also use high base-drive current under heavy loads. The MAX8510/MAX8511/MAX8512 do not suffer from these problems and consume only 40μA of quiescent current in light load and 220μA in dropout (see the Typical Operating Characteristics ).Output Voltage SelectionThe MAX8510/MAX8511 are supplied with factory-set output voltages from 1.5V to 4.5V, in 100mV increments (see Ordering Information ). The MAX8512 features a user-adjustable output through an external feedback net-work (see the Typical Operating Circuits ).To set the output of the MAX8512, use the following equa-tion:OUT REF V R1R2X -1V=where R2 is chosen to be less than 240kΩ and V REF = 1.225V. Use 1% or better resistors.PINNAMEFUNCTIONMAX8510MAX8511MAX8512SC70TDFN -EP SC70TDFN -EP SC70TDFN -EP 151515IN Unregulated Input Supply 232323GNDGround343434SHDN Shutdown.

Driving SHDN low disables the voltage reference, error amplifier, gate-drive circuitry, and pass transistor (see the Functional Diagram), and the device output enters a high-impedance state. Connect SHDN to IN for normal operation.Current LimitThe MAX8510/MAX8511/MAX8512 include a current lim-iter, which monitors and controls the pass transistor’s gate voltage, limiting the output current to 200mA. For design purposes, consider the current limit to be 130mA (min) to 300mA (max). The output can be shorted to ground for an indefinite amount of time without damaging the part. Thermal-Overload ProtectionThermal-overload protection limits total power dissipation in the MAX8510/MAX8511/MAX8512. When the junction temperature exceeds T J = +160°C, the thermal sensor signals the shutdown logic, turning off the pass transis-tor and allowing the IC to cool down. The thermal sensor turns the pass transistor on again after the IC’s junction temperature drops by 10°C, resulting in a pulsed output during continuous thermal-overload conditions.Thermal-overload protection is designed to protect the MAX8510/MAX8511/MAX8512 in the event of a fault con-dition. For continual operation, do not exceed the abso-lute maximum junction temperature rating of T J = +150°C. Operating Region and Power DissipationThe MAX8510/MAX8511/MAX8512 maximum power dis-sipation depends on the thermal resistance of the case and circuit board, the temperature difference between the die junction and ambient, and the rate of airflow. The power dissipation across the device is:P = I OUT (V IN - V OUT)The maximum power dissipation is:P MAX = (T J - T A) / (θJC + θCA)where T J - T A is the temperature difference between the MAX8510/MAX8511/MAX8512 die junction and the sur-rounding air, θJC is the thermal resistance of the package, and θCA is the thermal resistance through the PC board, copper traces, and other materials to the surrounding air. The GND pin of the MAX8510/MAX8511/MAX8512 per-forms the dual function of providing an electrical connec-tion to ground and channeling heat away. Connect the GND pin to ground using a large pad or ground plane.Noise ReductionFor the MAX8510, an external 0.01μF bypass capaci-tor between BP and OUT with innovative noise bypass scheme reduces output noises dramatically, exhibiting 11μV RMS of output voltage noise with C BP = 0.01μF and C OUT = 1μF. Startup time is minimized by a poweron cir-cuit that precharges the bypass capacitor. Applications InformationCapacitor Selectionand Regulator StabilityUse a 1μF capacitor on the MAX8510/MAX8511/MAX8512 input and a 1μF capacitor on the output. Larger input capacitor values and lower ESRs provide better noise rejection and line-transient response. Reduce output noise and improve load-transient response, stability, and power-supply rejection by using large output capacitors. Note that some ceramic dielectrics exhibit large capaci-tance and ESR variation with temperature. With dielec-trics such as Z5U and Y5V, it may be necessary to use a 2.2μF or larger output capacitor to ensure stability at temperatures below -10°C. With X7R or X5R dielectrics, 1μF is sufficient at all operating temperatures. A graph of the region of stable C OUT ESR vs. load current is shown in the Typical Operating Characteristics.Use a 0.01μF bypass capacitor at BP (MAX8510) for low-output voltage noise. The leakage current going into the BP pin should be less than 10nA. Increasing the capaci-tance slightly decreases the output noise. Values above 0.1μF and below 0.001μF are not recommended. Noise, PSRR, and Transient ResponseThe MAX8510/MAX8511/MAX8512 are designed to deliv-er ultra-low noise and high PSRR, as well as low dropout and low quiescent currents in battery-powered systems. The MAX8510 power-supply rejection is 78dB at 1kHz and 54dB at 100kHz. The MAX8511/MAX8512 PSRR is 72dB at 1kHz and 46dB at 100kHz (see the Power-Supply Rejection Ratio vs. Frequency graph in the Typical Operating Characteristics).When operating from sources other than batteries, improved supply-noise rejection and transient response can be achieved by increasing the values of the input and output bypass capacitors, and through passive filter-ing techniques. The Typical Operating Characteristics show the MAX8510/MAX8511/MAX8512 line- and load-transient responses.MAX8512Low-Dropout, 120mA Linear RegulatorsDropout VoltageA regulator’s minimum dropout voltage determines the lowest usable supply voltage. In battery-powered sys-tems, this determines the useful end-of-life battery volt-age. Because the MAX8510/MAX8511/MAX8512 use aP-channel MOSFET pass transistor, their dropout voltage is a function of drain-to-source on-resistance (RDS(ON)) multiplied by the load current (see the Typical Operating Characteristics ).MAX8512Low-Dropout, 120mA Linear RegulatorsFunctional Diagram*xy is the output voltage code (see Output Voltage Selector Guide).

General Description
The MAX1197 is a 3V, dual, 8-bit analog-to-digital converter (ADC) featuring fully differential wideband trackand-hold (T/H) inputs, driving two ADCs. The MAX1197 is optimized for low-power, small size, and high-dynamic performance for applications in imaging, instrumentation and digital communications. This ADC operates from a single 2.7V to 3.6V supply, consuming only 120mW while delivering a typical signal-to-noise and distortion (SINAD) of 48.5dB at an input frequency of 30MHz and a sampling rate of 60Msps. The T/H-driven input stages incorporate 400MHz (-3dB) input amplifiers. The converters may also be operated with singleended inputs. In addition to low operating power, the MAX1197 features a 3mA sleep mode as well as a 0.1µA power-down mode to conserve power during idle periods. An internal 2.048V precision bandgap reference sets the full-scale range of the ADC. A flexible reference structure allows the use of this internal or an externally applied reference, if desired, for applications requiring increased accuracy or a different input voltage range. The MAX1197 features parallel, CMOS-compatible threestate outputs. The digital output format can be set to two’s complement or straight offset binary through a single control pin. The device provides for a separate output power supply of 1.7V to 3.6V for flexible interfacing with various logic families. The MAX1197 is available in a 7mm x 7mm, 48-pin TQFP package, and is specified for the extended industrial (-40°C to +85°C) temperature range. Pin-compatible lower and higher speed versions of the MAX1197 are also available. Refer to the MAX1195 data sheet for 40Msps and the MAX1198 data sheet for 100Msps. In addition to these speed grades, this family will include a multiplexed output version (MAX1196, 40Msps), for which digital data is presented time interleaved and on a single, parallel 8-bit output port. For a 10-bit, pin-compatible upgrade, refer to the MAX1182 data sheet. With the N.C. pins of the MAX1197 internally pulled down to ground, this ADC becomes a drop-in replacement for the MAX1182. o Single 2.7V to 3.6V Operation o Excellent Dynamic Performance 48.5dB/45.3dB SINAD at fIN = 30MHz/200MHz 69dBc/53.5dBc SFDR at fIN = 30MHz/200MHz o -72dB Interchannel Crosstalk at fIN = 20MHz o Low Power 120mW (Normal Operation) 9mW (Sleep Mode) 0.3µW (Shutdown Mode) o 0.05dB Gain and ±0.05° Phase Matching o Wide ±1VP-P Differential Analog Input Voltage Range o 400MHz -3dB Input Bandwidth o On-Chip 2.048V Precision Bandgap Reference o User-Selectable Output Format—Two’s Complement or Offset Binary o Pin-Compatible 8-Bit and 10-Bit Upgrades Available
