Two of the microphones provide analog output signals and two of the microphones provide digital output signals. Top and bottom sound port options are provided for both the analog and the digital output microphones. External bypass capacitors are included on the power supply rails of the evaluation boards and DC blocking capacitors are placed in the analog output signal paths. A DC power supply of 1.6~3.6 Volts should be connected between the VDD and GND pins of the board to be evaluated. Please refer to the respective data sheets for proper connections to the remaining signal pins. cuidevices.comAdditional Resources: Product Page CUI Devices MODEL: DEVKIT-MEMS-001 DESCRIPTION: MICROPHONE DEVELOPMENT KIT date 04/06/2020 page 2 of 7 CIRCUIT DIAGRAMS & BOARD LAYOUTS Vdd1 Vdd2 C52 C62 Vdd Vdd 1 1 C51 C61 Out Out Out1 Out2 1 1 CMM-2718AB-38308-TR CMM-2718AT-42308-TR GND GND MIC1 MIC2 Vdd3 Vdd4 C72 C82 Sel3 Sel4 Vdd Vdd Sel Sel 1 1 Data Data Out3 Out4 Clock Clock GND Clock3 GND Clock4 CMM-4030DB-26354-TR CMM-4030DT-26354-TR MIC3 MIC4 cuidevices.com
