CS7250B Overview
The CS7250B is a high-performance digital MEMS microphone, offering class-leading total harmonic distortion (THD) performance, excellent SNR, and low power consumption. The CS7250B supports two operational modes, selected according to the applied clock frequency. Low Power Mode is ideal for always-on voice activity detection;.
