Description

The WM8786GEDS/V 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 WM8786GEDS/V 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.
