WM7120IMSE/RV 数据手册

WM7120, WM7120E

Top Port Analogue Silicon Microphone

DESCRIPTION

FEATURES

•

High SNR; selectable sensitivity tolerance options

The WM7120 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.

WM7120 - SNR 59dB, Sensitivity +/-3dB

WM7120E - SNR 59dB, Sensitivity +/-1dB

•

Low supply current 140μA

Low profile packaging

The

WM7120

incorporates

Wolfson’s

proprietary

CMOS/MEMS membrane technology, offering high reliability

and high performance in a miniature, low-profile package.

The WM7120 is designed to withstand the high

temperatures associated with automated flow solder

assembly processes. (Note that conventional microphones

can be damaged by this process.)

Support for automated flow solder assembly

Analogue output

Top Port Package

1.5V to 3.7V supply

3.76mm x 2.95mm x 1.10mm Package

The WM7120E 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.

APPLICATIONS

•

Mobile phone handsets

Portable media players

Digital still cameras

Digital video cameras

Bluetooth headsets

Portable navigation devices

Portable games consoles
