24-bit, 192kHz 8-Channel DAC  
DESCRIPTION  
FEATURES  
8-Channel DAC with PCM.  
Audio Performance  
103dB SNR (‘A’ weighted @ 48kHz) DAC  
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.  
DAC Sampling Frequency: 8kHz – 192kHz  
3-Wire SPI Serial or Hardware Control Interface  
Programmable Audio Data Interface Modes  
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.  
I2S, Left, Right Justified or DSP  
16/20/24/32 bit Word Lengths  
The audio data interface supports I2S, left justified, right  
justified and DSP digital audio formats.  
Four Independent stereo DAC outputs with independent  
digital volume controls  
Master or Slave Audio Data Interface  
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-pin  
SSOP.  
2.7V to 5.5V Analogue, 2.7V to 3.6V Digital supply  
Operation  
28 pin SSOP Package
