24-Bit, 192kHz Stereo ADC  
DESCRIPTION  
FEATURES  
SNR 111dB (‘A’ weighted @ 48kHz)  
THD -102dB (at -0.1dB)  
Sampling Frequency: 8 – 192kHz  
2 or 3 Wire Microprocessor Control Interface  
Master or Slave Clocking Mode  
The WM8785 is a stereo audio ADC with differential inputs  
designed for high performance recordable media applications.  
Data is provided as a PCM output.  
Stereo 24-bit multi-bit sigma-delta ADCs are used with digital  
audio output word lengths of 16 to 32 bits, and sampling rates  
from 8kHz to 192kHz. The device has a selectable high pass  
filter to remove residual DC offsets. The device also supports a  
TDM bus for data out.  
Programmable Audio Data Interface Modes  
-
-
I2S, Left, Right Justified or DSP  
16/20/24/32 bit Word Lengths  
A TDM bus is supported for data out  
Supply Voltages  
The device is controlled via a 2 or 3 wire serial interface. The  
interface provides access to all features including oversampling  
rate, audio format, powerdown, master/slave control and digital  
signal manipulation. The device is supplied in a 20-lead SSOP  
package.
