WM7132PE
Bottom Port Analog Silicon Microphone
DESCRIPTION
The WM7132P 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 WM7132P incorporates Cirrus proprietary
CMOS/MEMS membrane technology, offering high reliability
and high performance in a miniature, low-profile package.
The WM7132P 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 WM7132P Bottom Port microphone offers matched
performance to the WM7121P Top Port microphone. The
matched characteristics enable highly accurate sound pick-
up in opposite directions, suitable for noise cancellation and
other DSP algorithms.
The WM7132P offers a tight tolerance on the microphone
sensitivity, giving reduced variation between parts. This
removes the need for in-line production calibration of part-to-
part microphone variations.
FEATURES
High SNR (65dB)
Low variation in sensitivity (±1dB tolerance)
