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.)
FEATURES
High SNR (64.5dB)
Low variation in sensitivity (±3dB)
Low current consumption (180µA)
Analogue output
Bottom Port LGA Package
1.5V to 3.7V supply
APPLICATIONS
Mobile phone handsets
Wearable devices
Portable media players
Digital cameras
