DESCRIPTION
The WM7130A 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
WM7130A
incorporates
Wolfson’s
proprietary
CMOS/MEMS membrane technology, offering high reliability
and high performance in a miniature, low-profile package.
The WM7130A 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 WM7130AE variant offers a tighter 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; selectable sensitivity tolerance options
-
WM7130A - SNR 61dB, Sensitivity +/-3dB
-
WM7130AE - SNR 61dB, Sensitivity +/-1dB
Low supply current 140µA
Low profile packaging
Support for automated flow solder assembly
Analogue output
Bottom Port Package
1.5V to 3.7V supply
3.76mm x 3.00mm x 1.10mm Package
APPLICATIONS
Mobile phone handsets
Portable media players
Digital still cameras
Digital video cameras
Bluetooth headsets
Portable navigation devices
Portable games consoles
