WM7331E Bottom Port Analog Silicon Microphone DESCRIPTION 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. (Note that conventional microphones can be damaged by this process.
