INMP441 MEMS麦克风评估板说明书
UG-362 I2S Daughter Board User GuideGENERAL DESCRIPTIONThe EVAL-INMP441Z is an evaluation board that works with the EVAL-INMP441Z-FLEX and the Analog Devices’ system demonstration platform (SDP) to allow quick evaluation of the performance of the INMP441 MEMS microphone. This evaluation system can be used to stream two channels of audio from two INMP441 microphones to a PC over a USB connection. The system identifies itself to a PC as a standard USB audio interface; therefore, no additional drivers or software are required to run the system. One EVAL-INMP441Z-FLEX board is included in the evaluation kit. The SDP-B controller board is purchased separately from Analog Devices.The EVAL-INMP441Z board also provides hardware control and probe/test points to examine the digital signals of theINMP441.QUICK START GUIDETo quickly start up the evaluation board and capture audio on a PC, follow these steps. These steps are described in greater detail in the rest of this user guide.1.Connect at least one EVAL-INMP441Z-FLEX board to theEVAL-INMP441Z daughter board (see Figure 1).2.Connect the EVAL-INMP441Z daughter board to the SDP-B controller board.3.Connect a jumper across J9 and make sure that J8 is notpopulated.4.Push both switches of S1 to the right (enable) position.5.Provide a 5 V to 6 V supply to J4.6.Connect a mini-USB cable from a PC to J1 on the SDP-Bcontroller board.The PC should recognize the system as an audio interface using standard audio drivers. You can now use the microphones to record one or two channels of audio with any software that uses the standard audio driver (see the Software Setup section).PLEASE SEE THE LAST PAGE FOR AN IMPORTANT WARNING AND LEGAL TERMS AND CONDITIONS.HARDWARE OVERVIEWFigure 1 shows a photo of the EVAL-INMP441Z daughter board with one EVAL-INMP441Z-FLEX board plugged into the ZIF connector. Figure 2 shows the dimensions of the evaluation board.Figure 1.

The dc supply connected to J4 should be positive-tip. The micro-phones are configured to run with a single 1.8 V supply, but the supply can be set to either 2.5 V or 3.3 V by mounting a 0 Ω resistor on R17 or R11, respectively, and removing R18.LED D1 is illuminated when the board is powered on. With V DD = 1.8 V, the LED is only faintly lit.Power is supplied to the EVAL-INMP441Z-FLEX board through Voltage Regulator U5.The power supply connected to the EVAL-INMP441Z board also powers the SDP-B controller board through Connector J3. The microphone board requires only a few milliamps of current, but the SDP-B controller board requires up to 200 mA at 5 V.JumpersThe J8 and J9 jumper headers on the EVAL-INMP441Z board set the clock source and select the boot code.Header J8 does not need to be shorted with a jumper for the default clocking configuration. When J8 is populated, the 3.072 MHz crystal on the EVAL-INMP441Z board generates the master clock for the SPORT interface of the Blackfin® processor. By default, however, the microphone clocks are generated on the Blackfin processor.Header J9 selects the source of the code to boot the Blackfin processor on the SDP-B controller board. To use theevaluation system to stream USB audio to a PC, a jumper must be shorted across Header J9. Without the jumperpresent, the Blackfin processor boots the standard SDP code and does not perform USB streaming audio.These settings for J8 and J9 are illustrated in Figure 3.Figure 3. Top View of EVAL-IN MP441Z Board with Default Switchand Jumper Settings10432-00210432-003Document Number: UG-362--00 Page 2 of 9Revision: 1.1Rev Date: 04/28/2014UG-362SwitchesSwitch Block S1 has two SPST switches to control the CHIPEN pins of the two INMP441 microphones. When the switches are in the left position, the microphones are disabled; when the switches are in the right position, the microphones are enabled. Switch 1 (bottom switch) controls the leftmicrophone, and Switch 2 (top switch) controls the right microphone. The switch settings in Figure 3 show the microphones enabled.Flex Board ConnectionsThe EVAL-INMP441Z daughter board includes two headers, J1 and J2, to connect two INMP441 microphone flex boards (EVAL-INMP441Z-FLEX). The EVAL-INMP441Z-FLEX board connects all the pins of the INMP441 to copper contacts on the edge of the flex board.The EVAL-INMP441Z-FLEX board can be inserted directly into a ZIF connector, such as J1 or J2 on the EVAL-INMP441Zboard. A microphone connected to Header J1 is configured tooutput its data to the left channel of the I 2S data stream, and the microphone connected to Header J2 is configured to output its data to the right channel.The EVAL-INMP441Z-FLEX boards slide easily into the ZIF connectors on the EVAL-INMP441Z board. Follow these steps to install the flex boards.1. Loosen the black clamp on the J1 or J2 connector bypulling it to the right.2. Insert the flex board into the connector with the coppercontacts facing down.3. After the flex board is fully inserted, tighten the blackclamp to fasten the flex board in the connector. When properly connected, the sound port of the microphone is pointed up (see Figure 4). When two flex boards areconnected, the microphone sound ports are spaced 21 mm apart.Figure 4. EVAL-INMP441Z with Two Flex Boards Connected to an SDP-B Controller BoardSDP-B ConnectionThe EVAL-INMP441Z board connects to the Blackfin SDP-B controller board through Connector J3. The EVAL-INMP441Z board can be connected to either CON A or CON B on the SDP-B controller board; these two connectors provideidentical functionality. After you connect the EVAL-INMP441Z board to the SDP-B controller board but before you connect the USB jack of the SDP-B board to a PC, connect the power to the EVAL-INMP441Z board. After the system is powered on, you can connect the USB cable between the PC and J1 on the SDP-B controller board.The EVAL-INMP441Z board connects to the SDP-B controller board using a Hirose FX8-120P-SV1(91) connector on the SDP-B board. For more information about the SDP-B controller board, see the SDP User Guide (UG-277).The ADSP-BF527 Blackfin DSP on the SDP-B controller board is booted from code stored in the SPI flash memory IC (U7) on the EVAL-INMP441Z board.10432-004Document Number: UG-362--00 Page 3 of 9Revision: 1.1Rev Date: 04/28/2014UG-362I2S Monitoring HeaderThe I2S signal output from the INMP441 microphones canbe monitored on Header J7. The WS and SCK clock signals aresupplied from the SDP-B controller board, whereas the SDdata signal is output from the microphones. Note that HeaderJ7 cannot be used to supply clocks directly to themicrophones because the level translator (U6) is configuredto always drive the clock signals.SOFTWARE SETUPThe SDP-B/EVAL-INMP441Z system does not require newsoftware to be installed on the PC. The system identifies itselfas a standard audio class device and uses the standardWindows® audio drivers. Therefore, the system can be usedby any PC software that can record audio through thestandard drivers.The EVAL-INMP441Z board is identified in the WindowsDevice Manager as INMP441 USB Audio (see Figure 5).One or two channels of audio can be recorded at a samplerate of 48 kHz.Figure 5. Windows Device ManagerThe evaluation system functions as a USB audio device inWindows XP, Windows Vista®, and Windows 7. The PC audiosettings show both a Microphone and a Line setting forINMP441 USB Audio. These items have identical function-ality; either can be selected with no functional differences.The sensitivity of the IN MP441 is −26 dBFS. If the microphoneis used to record voices at normal conversational levels, thelevel of the recording may be somewhat low. To boost thelevel of the recorded audio, try applying gain to the signal in therecord path of the recording software (a gain of 10 dB to 20 dB isrecommended).The following sections provide instructions for setting upseveral popular software tools to listen and record with theEVAL-INMP441Z system.Windows Sound SettingsYou can control the properties of the INMP441 USB audiodevice in Windows as follows. (The following steps and thescreenshot in Figure 6 are for Windows 7. For other versionsof Windows software, this procedure may vary.)1.Right-click the speaker icon in the taskbar and selectRecording devices.2.Ensure that the IN MP441 USB audio microphone device isenabled and active.3.Select Properties for the device to display the MicrophoneProperties window.4.In the Microphone Properties window, click the Listen tab(see Figure 6).Figure 6. Windows Microphone Properties Window5.Select the box labeled Listen to this device and click Apply.The Listen to this device option allows you to loop themicrophone audio back to the audio output of the PC,either through the internal speakers or throughexternally connected headphones or speakers.1432-51432-6Document Number: UG-362--00 Page 4 of 9Revision: 1.1Rev Date: 04/28/2014UG-362You should now be able to hear the microphone audiodirectly on the PC audio output. If you are using speakersinstead of headphones with your PC, do not place themicrophones too close to the speakers because audiblefeedback can be created.Audacity Sound SettingsAudacity® is a free audio recording and editing tool. To recordaudio using the EVAL-INMP441Z system, you can select eitherMicrophone (INMP441 USB Audio) or Line (INMP441 USBAudio) as the recording device in the Audacity Preferenceswindow (see Figure 7). The version tested was Audacity 1.3.Figure 7. Audacity Preferences WindowAdobe Audition SettingsAudition® is the Adobe® multitrack audio recording tool. Torecord audio using the EVAL-INMP441Z system, you canselect either Microphone (INMP441 USB Audio) or Line(INMP441 USB Audio) as the default input in the AuditionPreferences window (see Figure 8).

AMC1210,it could be possible to reduce the value of the series resistor R47.AMC1210EVM 2SLAU185–August 20061.3Power Supply 2EVM Operation EVM OperationThe AMC1210modular EVM requires two supply voltages and two optional supply voltages.A5-Vdc voltage is needed for the ADS1204and the core of the AMC1210.A variable supply in the range of2.7 Vdc to5Vdc is needed for the interface pins of the AMC1210.In addition,a±15-V supply is necessary if the PWM driver operational amplifier OPA1632is used.If the AMC1210modular EVM is used incombination with theBoard,J06provides connection to the common power busdescribed in the documentWhen used as a stand-alone EVM,the power supplies can be applied to J01and J02.While filters are provided for all four power supplies,optimal performance of the EVM requires a clean,well-regulatedpower source.To configure a desired interface mode of the AMC1210the jumpers JP09,JP10,and JP16are used.Jumper DescriptionJP09JP10JP16Open Open Open SPI interface

MAX25603EVKIT#Click here to ask an associate for production status of specific part numbers.MAX25603 Evaluation KitEvaluates: MAX25603319-100847; Rev 0; 12/21General DescriptionThe MAX25603 evaluation kit (EV kit) provides a provendesign to evaluate the MAX25603 automotive high-voltage, high-brightness LED buck-boost controller. The EV kit operates from a 5V to 60V DC supply voltage. The EV kit is configured to deliver up to 1A to one or two strings of 1 to 15 LEDs. The total voltage of each string can vary from 0V to 60V. The anode of the LED strings should go to LED1+ or LED2+ terminals and the cathodes to the GND terminal. Shunting FETs are provided to emulate a combination headlamp in which a single LED string can contain the clearance lamp (CLL), low beam (LB), and high beam (HB) all in one. Each can be independently turned on or off by shorting across the appropriate segments of the LED string.Features•5V to 60V Input Voltage Range•Demonstrates Use in Combination Headlamps and Multistring, Time-Sharing Applications •Analog and Digital Dimming Control •Input Current Limit•LED Current Clamp Function•Output Discharge for Faster Transient Time •LED Short and Open Protection •Proven PCB Layout•Fully Assembled and TestedOrdering Information appears at end of data sheet.Quick StartRequired Equipment•MAX25603 EV kit•12V, 5A DC power supply •Signal generator•Series-connected LED strings rated to at least 1.5A •Oscilloscope with a current probeProcedureThe EV kit is fully assembled and tested. Use the following steps below to verify board operation:Caution: Do not turn on power supply until all connections are made. Be sure not to violate power ratings if modifying component values.1.Verify that all jumpers are in their default positions, asshown in Table 1.2.Connect the positive terminal of the 12V supply toVINP1 and the negative terminal to the PGND.3.Connect the anode a LED string to LED1+ and thecathode to GND on the EV kit.4.Clip the current probe on the wire connected to the LEDstring.5.Turn on the DC power supply.6.Apply 5V to EN1.7.Verify that the LEDs turn on.8.Adjust potentiometer R3 until the LED current isapproximately 1A.EV Kit PhotoMAX25603 Evaluation KitEvaluates: MAX2560319-XXXXXX; Rev 0; MM/YYTable 1. Jumper Connection GuideSetup and Operation1.Verify that all jumpers are in their default positions, as shown in Table 1.2.Connect the positive terminal of the 12V supply to VINP1 and the negative terminal to the PGND.3.Connect the anode a LED string to LED1+ and the cathode to GND on the EV Kit.4.Clip the current probe on the wire connected to the LED string.5.Turn on the DC power supply.6.Apply 5V to EN1.7.Verify that the LEDs turn on.8.Adjust potentiometer R3 until the LED current is approximately 1A.Clearance Lamp (CCL), Low Beam (LB), High Beam (HB)Shunting FETs Q7, Q9, Q10, and Q11 are provided to emulate an application in which a single MAX25603 device can drive the clearance lamp, daytime running lamps, low beam, and high beam functions all from a single LED string. The following procedure describes how to configure this EV kit to drive the LED configuration shown in Typical Application Circuit .MAX25603 Evaluation Kit Evaluates: MAX256039.With jumper J6 closed, connect the daytime running lamp LEDs between LED2+ and DRL-. The clearance lampLEDs are connected between DRL- and LB.10.Short LED1+ to LB+. The low beam LEDs are connected between LB+ and HB. The high beam LEDs areconnected between HB and GND.11.Controlling each individual segment is done by driving the gates of the appropriate shunting FETs high or low.The clearance lamp and daytime running lamps can be dimmed simultaneously by applying a 5V 200Hz PWM signal at EN1. While EN1 is low, EN2 must be high to conduct the clearance and daytime running lamps. A level shifter is provided for driving the gate of the Q7 pMOS.12.Apply a 5V signal to the gate of Q8 to turn the daytime running lamps off. If desired, the SHUNT pin can be tiedto EN1. When SHUNT is low, the error amplifier of the MAX25603 uses the compensation network on COMP1.COMP2 is connected to the error amplifier when SHUNT is high. Using the SHUNT pin also enables the output discharge feature.Detailed Description of HardwareThis evaluation kit should be used with the following documents:•MAX25603 data sheet•MAX25603 EV kit data sheet (this document)These documents, or links to them, are included on the MAX25603 EV kit package. For the latest versions of the documents listed above, use the following link: /MAX25603EN1 and EN2—PWM DimmingEN1 and EN2 are input signals that control GTP1 and GTP2, respectively, as well as the switching of MAX25603. If both EN1 and EN2 are low, the MAX25603 is in the off state. If both EN1 and EN2 are high, EN1 has priority, and GTP1 is on while GTP2 is off. PWM dimming can be achieved on either channel by keeping the respective jumper J4 or J5 open and applying an external PWM signal to either EN1 or EN2. Move either jumper to position 1-2 keeps that channel on 100% and moving that jumper to 2-3 keeps that channel off. If simultaneously toggling between EN1 and EN2, ensure that there is at least a 1µs deadtime between the falling edge of one EN and the rising edge of the other EN. For the typical application circuit in Figure 1, keep EN2 high and toggle EN1 to implement PWM dimming on the CLL and DRL LEDs. Analog Dimming Control (ICTRL)When J1 is closed, the LED current is set by resistive divider from VCC. The equation to set the LED current is:I LED=(V ICTRL−200mV)/(5×R24||R25)Use a screwdriver to turn the potentiometer R3 to adjust ICTRL. If ICTRL is greater than 1.3V, the LED current is limited to:I LED=1.1V/(5×R24||R25)For time sharing applications in which EN1 and EN2 are alternately dimmed, a different LED current setting can be desired on each string. R4 and Q1 are provided to lower the programmed current. Place jumper J2 in position 1-2 for a lower LED current on the EN2 or in position 2-3 for a lower LED on the EN1 string. By default, J2 is open and the LED current is the same for both strings. Analog Devices | 3MAX25603 Evaluation KitEvaluates: MAX25603 Analog Devices | 4LED Current Clamp and Output DischargeWhen closing any of the shunting FETs, the total LED string voltage is initially too high that causes the LEDs to conduct a large amount of current until the output capacitor decreases to the appropriate value for the desired programmed current. A unique feature with the MAX25603 is the ability to drive the PMOS on GTP1 and GTP2 as linear current clamps to limit the LED current and protect the LEDs. This clamp level is set to 25% greater than the current set by ICTRL. If the current clamp is triggered concurrently to a rising edge on the SHUNT pin, the MAX25603 switches in a hysteretic mode to provide negative inductor current and discharge the output capacitor back to the supply. The LED current clamp improves robustness of the system while utilizing the dual compensation and output discharge of SHUNT pin greatly improves transient performance.Input-Current LimitThe MAX25603 features circuitry that limits the input current during line dropouts. Refer to the MAX25603 IC data sheet for details on setting the input current limit. The input current is given by the following equation:IN MAX =0.1RN1||RN2This circuitry can be disabled by replacing RN1 and RN2 with 0Ω resistors.Open LEDThe MAX25603 features an adjustable overvoltage threshold used for open LED detection. The threshold is determined by the voltage divider on the FB pin and is given by the following equation:V OVP =1.24×R45+R46R46The overvoltage threshold level should be set to approximately 25% above the expected LED forward voltage. When driving the LEDs with a very narrow PWM duty cycle, overvoltage may not be detected if the overvoltage level is set too high and the output cannot slew up to it within the PWM on-time. This can arise when driving two strings with a largely different number of LEDs. R49 and Q3 are provided as way to lower the threshold. By default, J8 is open and the overvoltage threshold is set to 35V for both EN1 and EN2. Select an appropriate value for R49 and short jumper J8 between 1-2 or 2-3 depending on if either EN1 or EN2 requires the lower threshold.When an open is detected, switching stops and FLT is pulled low. Switching resumes only when the voltage on the FB drops by 70mV and EN1 or EN2 is high. FLT goes high only if EN1 or EN2 is high and V(ISP-ISN) is greater than 20mV.Short LEDA short-circuit condition across the LED string is detected when the voltage on ISP falls below 4.7V for at least 10ms. After 10ms the regulation point of the voltage across the LED current-sense resistor is determined by the lower of 320mV or ICTRL. A short-circuit does not assert FLT. The short-circuit condition is cleared when ISP rises above 4.8V.MAX25603 Evaluation Kit Evaluates: MAX25603 Typical Application CircuitOrdering Information Analog Devices | 5MAX25603 Evaluation Kit Evaluates: MAX25603 MAX25603 EV Kit Bill of Materials Analog Devices | 6MAX25603 Evaluation Kit Evaluates: MAX25603 Analog Devices | 7MAX25603 Evaluation Kit Evaluates: MAX25603 Analog Devices | 8MAX25603 Evaluation Kit Evaluates: MAX25603MAX25603 EV Kit Schematic Analog Devices | 9 Analog Devices | 10MAX25603 EV Kit PCB LayoutMAX25603 EV Kit Component Placement Guide —Top SilkscreenMAX25603 EV Kit PCB Layout —Layer 2 MAX25603 EV Kit PCB Layout —Top MAX25603 EV Kit PCB Layout —Layer 3MAX25603 EV Kit PCB LayoutMAX25603 EV Kit PCB Layout—Bottom Analog Devices | 11MAX25603EVKIT#。
