24-bit 192kHz Stereo DAC  
DESCRIPTION  
FEATURES  
Stereo DAC  
The WM8727 is a high performance stereo DAC designed  
for audio applications such as DVD, home theatre systems,  
and digital TV. The WM8727 supports data input word  
lengths from 16 to 24-bits and sampling rates up to 192kHz.  
The WM8727 consists of a serial interface port, digital  
interpolation filters, multi-bit sigma delta modulators and  
stereo DAC in a very small 8-lead SOIC package.
