WM7211E Top Port Digital Silicon Microphone DESCRIPTION The WM7211 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 WM7211 incorporates Cirrus’s proprietary CMOS/MEMS membrane technology, offering high reliability and high performance in a miniature, low-profile package. The WM7211 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 WM7211 incorporates a high performance ADC, which outputs a single-bit data stream using Pulse Density Modulation (PDM) encoding.
