描述：The EVAL-ADMP521Z-FLEX is an bottom-ported, Digital output, MEMS microphone evaluation board. This flex PCB includes just the ADMP521 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-ADMP521Z-FLEX boards can share common data, clock, VDD and ground signals to multiplex both microphone signals on a common data line. The EVAL-ADMP521Z-FLEX is a simple evaluation board that allows quick evaluation of the performance of the ADMP521 MEMS microphone. The small size and low profile of the flexible PCB enable direct placement of the microphone into a prototype or an existing design for an in-situ evaluation. The EVAL-ADMP521Z-FLEX consists of an ADMP521 microphone and a 0.1μF bypass capacitor soldered to a flexible PCB with colour-coded wires attached. .
