Mic Noise Cancelling -38dB 3.6V Solder Pad

The WM7331 is a low-profile silicon analog microphone. It offers high Signal to Noise Ratio (SNR) and low power consumption and is suited to a wide variety of consumer applications.The WM7331 incorporates Cirrus Logic 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 within an extremely small package size.The WM7331 is designed to withstand the high temperatures associated with automated flow solder assembly processes. The WM7331 offers tight tolerance on the microphone sensitivity, giving reduced variation between parts. This removes the need for in-line production calibration of part-topart microphone variations.
