Cirrus Logic Inc. WM8781GEDS/V

Description
The WM8781 is a high-performance, low-cost stereo audio ADC designed for recordable media applications. It offers stereo line level inputs and two control input pins (FORMAT, IWL) for operation in three industry standard audio interface modes. An internal op-amp on the front end accommodates analogue input signals greater than 1V. A high pass filter removes residual DC offsets.
The WM8781 supports Master or Slave mode clocking schemes. A control input pin (M/S) allows for Slave mode or Master mode operation. A stereo 24-bit multi-bit sigma-delta ADC is used with 128x, 64x, or 32x over-sampling, depending on the sample rate. Digital audio output word lengths from 16-24 bits and sampling rates from 8kHz to 192kHz are supported.
The device is hardware controlled and comes in a 20-lead SSOP package.
