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. cui.com Additional Resources: Product Page CUI Inc MODEL: DEVKIT-MEMS-001 DESCRIPTION: MICROPHONE DEVELOPMENT KIT date 05/14/2019 page 2 of 7 CIRCUIT DIAGRAMS & BOARD LAYOUTS Vdd1 C52 1 Vdd2 Vdd Out C51 1 GND Vdd3 C72 Vdd 1 cui.com Out1 Sel3 Sel Data Vdd4 C82 Vdd 1 Out3 Clock3 CMM-4030DB-26354-TR MIC3 Out C61 1 CMM-2718AB-38308-TR GND MIC1 Clock GND C62 Vdd 1 CMM-2718AT-42308-TR MIC2 Sel4 Sel Data Clock GND Out2 Out4 Clock4 CMM-4030DT-26354-TR MIC4 Additional Resources: Product Page CUI Inc MODEL: DEVKIT-MEMS-001 DESCRIPTION: MICROPHONE DEVELOPMENT KIT date 05/14/2019 page 3 of 7 CMM-2718AB-38308-TR WWW.CUI.COM/PRODUCT/AUDIO/MICROPHONES/MEMS-MICROPHONES/CMM-2718AB-38308-TR ELECTRICAL parameter conditions/description directivity omnidirectional sensitivity (S) at 94 dB SPL, 1 kHz supply voltage (VDD) current consumption (IDSS) VDD = 2.0 V sensitivity reduction VDD = 3.6 ~ 1.6 V frequency (f) min typ max units -41 -38 -35 dB 1.6 2.0 3.6 V 80 A -0.5 dB 100 10,000 at 94 dB SPL, 1 kHz (A-weighted) total harmonic distortion (THD) at 94 dB SPL, 1 kHz 0.2 % acoustic overload point (AOP) at 10% THD, 1 kHz 130 dB SPL output impedance (Zout) at 1 kHz Notes: 65 Hz signal to noise ratio (S/N) dBA 300 1.
