The WM7331 is a low-profile silicon analog microphone offering high Signal-to-Noise Ratio (SNR) and low power consumption. The device incorporates Cirrus Logic’s proprietary CMOS\/MEMS membrane technology, offering high reliability and high performance in a miniature, low-profile package. The compact integration of transducer and internal circuitry on a single die enables implementation with an extremely small package. The WM7331 offers tight tolerance on the microphone sensitivity, giving reduced variation between parts and removing the need for in-line production calibration of part-to-part microphone variations.
