WM7121PE Top Port Analog Silicon Microphone DESCRIPTION The WM7121P 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 WM7121P incorporates Cirrus Logic® proprietary CMOS/MEMS membrane technology, offering high reliability and high performance in a miniature, low-profile package. The WM7121P 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 WM7121P Top Port microphone offers matched performance to the WM7132P Bottom Port microphone.
