The WM8768 is a multi-channel audio DAC ideal for DVD
and surround sound processing applications for home hi-fi,
automotive and other audio visual equipment.
Four 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. Each DAC channel has
independent digital volume and mute control.
The audio data interface supports I

S, left justified, right
justified and DSP digital audio formats.
The device is controlled either via a 3 wire serial interface or
directly using the hardware interface. These interfaces
provide access to features including channel selection,
volume
controls,
mutes,
management facilities. The device is available in a 28-pin
SSOP.
