WM7230E Bottom Port Digital Silicon Microphone DESCRIPTION The WM7230 is a low-profile silicon digital microphone. It offers high Signal to Noise Ratio (SNR) and low power consumption and is suited to a wide variety of consumer applications. The WM7230 incorporates Cirrus Logic proprietary CMOS/MEMS membrane technology, offering high reliability and high performance in a miniature, low-profile package. The WM7230 is designed to withstand the high temperatures associated with automated flow solder assembly processes. (Note that conventional microphones can be damaged by this process.) The WM7230 incorporates a high performance ADC, which outputs a single-bit data stream using Pulse Density Modulation (PDM) encoding.
