WM8716  
High Performance 24-bit, 192kHz Stereo DAC  
Production Data, April 2001, Rev 3.1  
DESCRIPTION  
FEATURES  
112dB SNR (‘A’ weighted @ 48kHz), THD: -97dB @  
-1dB FS  
The WM8716 is a high performance stereo DAC designed  
for audio applications such as CD, DVD, home theatre  
systems, set top boxes and digital TV. The WM8716  
supports data input word lengths from 16 to 24-bits and  
sampling rates up to 192kHz. The WM8716 consists of a  
serial interface port, digital interpolation filter, multi-bit sigma  
delta modulator and stereo DAC in a small 28-pin SSOP  
package. The WM8716 also includes a digitally controllable  
mute and attenuator function on each channel.  
Sampling frequency: 8kHz to 192kHz  
Selectable digital filter roll-off  
Optional interface to industry standard external filters  
Differential mono mode  
Input data word: 16 to 24-bit  
Hardware or SPI compatible serial port control modes:  
Hardware mode: mute, de-emphasis, audio format  
control  
The internal digital filter has two selectable roll-off  
characteristics. A sharp or slow roll-off can be selected  
dependent on application requirements. Additionally, the  
internal digital filter can be by-passed and the WM8716  
used with an external digital filter.  
Serial mode: mute, de-emphasis, attenuation (256  
steps), phase reversal  
Compatible upgrade to PCM1716  
The WM8716 supports two connection schemes for audio  
DAC control. The SPI-compatible serial control port  
provides access to a wide range of features including on-  
chip mute, attenuation and phase reversal. A hardware  
controllable interface is also available.  
APPLICATIONS  
CD, DVD audio  
Home theatre systems  
Set top boxes  
Digital TV
