DESCRIPTION
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). WM8951L Stereo ADC with Microphone Input and Clock Generator FEATURES
