24-bit, 192kHz 8-Channel DAC
WM8768
DESCRIPTION
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 I2S, 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, de-emphasis and power
management facilities. The device is available in a 28-lead
SSOP.
