ADMP621 FLEX Evaluation Board

製品詳細

Analog Devices has sold its MEMS Microphone product line to InvenSense.
Please visit the InvenSense ADMP621 product page for all technical support and sales information.

This flex PCB includes just the ADMP621 and a bypass capacitor. The five wires allow an easy connection to the microphone’s PDM output data, clock, left/right select, VDD, and ground into your evaluation system. Two EVAL-ADMP621Z-FLEX boards can share common data, clock, VDD, and ground signals to multiplex both microphone signals on a common data line.
