24-bit, 192kHz 6-Channel DAC
WM8766
DESCRIPTION
The WM8766 is a multi-channel audio DAC 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. 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 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.
