WM8731L General Description

The WM8731 or WM8731L (WM8731/L) are low power stereo CODECs with an integrated headphone driver. The WM8731/L is designed specifically for portable MP3 audio and speech players and recorders. The WM8731 is also ideal for MD, CD-RW machines and DAT recorders.

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 and DACs are used with oversampling digital interpolation and decimation filters.

Digital audio input word lengths from 16-32 bits and sampling rates from 8kHz to 96kHz are supported.
Stereo audio outputs are buffered for driving headphones from a programmable volume control, line level outputs are also provided along with anti-thump mute and power up/down circuitry.

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

The interface provides access to all features including volume controls, mutes, de-emphasis and extensive power management facilities. The device is available in a small 28- lead SSOP package or the smaller 28 lead quad flat leadless package (QFN).

WM8731L Maximum Ratings

CONDITION	MIN	MAX
Digital supply voltage	-0.3V	+3.63V
Analogue supply voltage	-0.3V	+3.63V
Voltage range digital inputs	DGND -0.3V	DVDD +0.3V
Voltage range analogue inputs	AGND -0.3V	AVDD +0.3V
Operating temperature range, TA	-25	+85
