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.
