FEATURES

• 4 detachable evaluation boards
• 1 analog MEMS that is compatible for ECM drop-in replacement
• 1 noise cancelling, 1 unidirectional, & 1 omnidirectional ECM included
• plated through hole I/O terminals for multiple testing options EVAL BOARD circuit technology output acoustic size sensitivity current port dia (mm) typ (dB) typ (μA) CMM-3312AT-44308-TR MIC5 MEMS analog top 3.3 -44 80 CMR-2747PB-A MIC6 ECM analog top 6.0 -47 500 CMC-6015-47P MIC7 ECM analog top 6.0 -47 500 CMC-4013-SMT-TR MIC8 ECM analog top 4.0 -42 500 OPERATIONAL INSTRUCTIONS The CUI Devices electret condenser microphone (ECM) evaluation board consists of four independent microphone evaluation circuits. One of the microphones is constructed to be noise cancelling, one is constructed to provide unidirectional sound capture, one is constructed to provide omnidirectional sound capture and the fourth microphone is an analog output MEMS microphone with the two pin connections configured in a similar manner to the ECMs. 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 2~10 Volts should be connected between the VDD and GND pins for the ECM evaluation circuits. A DC power supply of 1.6~3.6 Volts should be connected between the VDD and GND pins for the MEMS microphone evaluation circuit. The recommended operating voltage for all of the evaluation boards is 2 V. Please refer to the respective data sheets for additional information regarding each of the microphones.
