WM8781GEDS/V Datasheet PDF - Cirrus Logic

DESCRIPTION
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 accommodate analogue input signals greater than 1Vrms. The device also has a high pass filter to remove residual DC offsets.
