WM8786
24-bit, 192kHz Stereo ADC
DESCRIPTION
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.
