DESCRIPTION  
FEATURES  
Stereo DAC  
The WM8714 is a high performance stereo DAC designed  
for audio applications such as DVD, home theatre systems,  
and digital TV. The WM8714 supports data input word  
lengths from 16 to 24-bits and sampling rates up to 96kHz.  
The WM8714 consists of a serial interface port, digital  
interpolation filters, multi-bit sigma delta modulators and  
stereo DAC in a 14-pin SOIC package.  
Audio Performance  
-
-
95dB SNR (‘A’ weighted @ 48kHz) DAC
