24-Bit, 192kHz Stereo ADC
WM8785
DESCRIPTION
FEATURES
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.
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.
