Figure 12. Stereo PDM Microphone Connection to Codec

Decouple the VDD pin of the INMP522 to GND with a 0.1 µF capacitor. Place this capacitor as close to VDD as the printed circuit board

(PCB) layout allows.

Do not use a pull-up or pull-down resistor on the PDM data signal line because the resistor can pull the signal to an incorrect state

during the period that the signal line is tristated.
