24-Bit, 192kHz Stereo ADC
WM8786
DESCRIPTION
FEATURES
The WM8786 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 also has a high pass filter to
remove residual DC offsets.
The device is hardware controlled. Pin programming 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.
