EVAL-ADMP421Z-FLEX, PDM Digital Output MEMS Microphone Evaluation Board based on ADMP421

EVAL-ADMP421Z-FLEX, Evaluation Board allows quick evaluation of the performance of ADMP421 PDM output MEMS microphones in a package with 4.00 mm × 3.00 mm footprint size. The small size and low profile of the flexible printed circuit board (PCB) enable direct placement of the microphone into a prototype or an existing design for an in situ evaluation. The evaluation board consists of a bottom port microphone and 0.1 uF bypass capacitor soldered to a flexible PCB with color-coded wires attached. Stereo PDM microphones can be evaluated by connecting the DATA wires from two flex boards, while tying the L/R SELECT wire of one to VDD and the other to GND
