WM8763 General Description

The WM8763/4/5 are multi-channel audio DACs ideal for DVD and surround sound processing applications for home hi-fi, automotive and other audio visual equipment.

Three stereo 24-bit multi-bit sigma delta DACs are used with oversampling digital interpolation filters. Digital audio input word lengths from 16-32 bits and sampling rates from 8kHz to 192kHz are supported.

The audio data interface supports either 16-24-bit I2S, 16- 24-bit left justified, or 24-bit right justified digital audio formats.

The devices are controlled directly using the hardware interface. All members of the family are available in a 20-pin SSOP.

WM8766 General Description

The WM8766 is a multi-channel audio DAC ideal for DVDand surround sound processing applications for home hi-fi,automotive and other audio visual equipment.

Three stereo 24-bit multi-bit sigma delta DACs are usedwith oversampling digital interpolation filters. Digital audioinput word lengths from 16-32 bits and sampling rates from8kHz to 192kHz are supported. Each DAC channel hasindependent digital volume and mute control.

The audio data interface supports I2S, left justified, rightjustified and DSP digital audio formatsThe device is controlled via a 3 wire serial interface ordirectly using the hardware interface. These interfacesprovide access to features including channel selection,volume controls, mutes, de-emphasis and powermanagement facilities. The device is available in a 28-pinSSOP.
