24-bit, 192kHz Stereo CODEC with 5 Channel I/P Multiplexer  
DESCRIPTION  
FEATURES  
Audio Performance  
The WM8776 is  
a high performance, stereo audio  
CODEC with five channel input selector. The WM8776 is  
ideal for surround sound processing applications for  
home hi-fi, DVD-RW and other audio visual equipment.  
108dB SNR (‘A’ weighted @ 48kHz) DAC  
102dB SNR (‘A’ weighted @ 48kHz) ADC  
DAC Sampling Frequency: 32kHz – 192kHz  
ADC Sampling Frequency: 32kHz – 96kHz  
A stereo 24-bit multi-bit sigma delta ADC is used with a  
five stereo channel input mixer. Each ADC channel has  
programmable gain control with automatic level control.  
Digital audio output word lengths from 16-32 bits and  
sampling rates from 32kHz to 96kHz are supported.  
Five stereo ADC inputs with analogue gain adjust from  
+24dB to –21dB in 0.5dB steps  
Programmable Limiter or Automatic Level Control (ALC)  
Stereo DAC with independent analogue and digital  
volume controls  
A stereo 24-bit multi-bit sigma delta DAC is used with  
digital audio input word lengths from 16-32 bits and  
sampling rates from 32kHz to 192kHz. The DAC has an  
input mixer allowing an external analogue signal to be  
mixed with the DAC signal. There are also Headphone  
and line outputs, with volume controls for the  
headphones.  
Stereo Headphone and Line Output  
3-Wire SPI Compatible or 2-Wire Software Serial  
Control Interface  
Master or Slave Clocking Mode  
Programmable Audio Data Interface Modes  
I2S, Left, Right Justified or DSP  
The WM8776 supports fully independent sample rates  
for the ADC and DAC. The audio data interface supports  
I2S, left justified, right justified and DSP formats.  
16/20/24/32 bit Word Lengths  
Analogue Bypass Path Feature  
Selectable AUX input to the volume controls  
The device is controlled in software via a 2 or 3 wire  
serial interface, selected by the MODE pin, which  
provides access to all features including channel  
selection, volume controls, mutes, and de-emphasis  
facilities.  
2.7V to 5.5V Analogue, 2.7V to 3.6V Digital supply  
Operation  
The device is available in a 48-pin TQFP package.  
APPLICATIONS  
Surround Sound AV Processors and Hi-Fi systems  
DVD-RW
