WM8781 Overview
The WM8781 is a high performance, low cost stereo audio ADC designed for recordable media applications. The device offers stereo line level inputs along with two control input pins (FORMAT, IWL) to allow operation of the audio interface in three industry standard modes. An internal op-amp is integrated on the front end of the chip to acmodate analogue input signals greater than 1Vrms.
