DESCRIPTION

The WM8788 is a high performance 24-bit stereo ADC designed for LCD televisions, DVD, Blu-Ray and set-top box applications.

A stereo pair of analogue inputs is provided; external resistors are used to configure the device for line level inputs at 1Vrms or for higher input signal levels. The Hi-Fi ADCs output 16, 20 or 24-bit stereo data on the digital audio interface.
