DESCRIPTION

The WM8951L is a low power stereo ADC with an

integrated microphone interface and crystal oscillator for

clock generation. The WM8951L is ideal for voice recorders,

wireless microphones and games console accessories.

Stereo line and mono microphone level audio inputs are

provided, along with a mute function, programmable line

level volume control and a bias voltage output suitable for

an electret type microphone.

Stereo 24-bit multi-bit sigma delta ADCs are used with

oversampling decimation filters. Digital audio input word

lengths from 16-32 bits and sampling rates from 8kHz to

96kHz are supported.

The device is controlled via a 2 or 3 wire serial interface.

The interface provides access to all features including

volume controls, mutes and extensive power management

facilities. The device is available in a small 28 lead 5x5mm

quad flat leadless package (QFN).
