WM7133L
Bottom Port Analogue Silicon Microphone
DESCRIPTION
The WM7133L is a low-profile silicon analogue microphone.
It offers high Signal to Noise Ratio (SNR) and low power
consumption and is suited to a wide variety of consumer
applications.
The WM7133L incorporates Wolfson’s proprietary
CMOS/MEMS membrane technology, offering high reliability
and high performance in a miniature, low-profile package.
The WM7133L is designed to withstand the high
temperatures associated with automated flow solder
assembly processes. (Note that conventional microphones
can be damaged by this process.)
