WM7230, WM7230E

Bottom Port Digital Silicon Microphone

DESCRIPTION

FEATURES

•

High SNR; selectable sensitivity tolerance options

The WM7230 is a low-profile silicon digital microphone. It

offers high Signal to Noise Ratio (SNR) and low power

consumption and is suited to a wide variety of consumer

applications.

WM7230 – SNR 61dB, Sensitivity +/-3dB

WM7230E – SNR 61dB, Sensitivity +/-1dB

•

Low power

The WM7230 incorporates Wolfson’s proprietary

CMOS/MEMS membrane technology, offering high

reliability and high performance in a miniature, low-profile

package. The WM7230 is designed to withstand the high

temperatures associated with automated flow solder

assembly processes. (Note that conventional microphones

can be damaged by this process.)

Sleep Mode - 2μA

Normal Operation - 700μA

•

Low profile packaging

Support for automated flow solder assembly

PDM Digital audio output

Stereo/array operation

Proprietary ADC technology

The WM7230 incorporates a high performance ADC,

which outputs a single-bit Pulse Density Modulated (PDM)

audio data stream. The WM7230 supports selectable

left/right channel assignment for a two-channel digital

microphone interface, enabling efficient connection of

multiple microphones in stereo/array configurations.

Reduced clock jitter sensitivity

Low noise floor modulation

Stable in overload condition

•

Bottom Port Package

1.64V to 3.7V supply

The WM7230E 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.

4.00 mm x 3.00 mm x 1.00mm Thin Package Design
