Description

The WM8738 is a high performance stereo audio ADCdesigned for consumer applications.

Stereo line-level audio inputs of the WM8738 are provided, along with acontrol input pin to allow operation of the audio interface ineither one of two industry standard modes. The device alsohas a selectable digital high pass filter to remove residualDC offsets.

Stereo 24-bit multi-bit sigma delta ADCs of the WM8738 are provided, alongwith oversampling digital interpolation filters. 24-bit digitalaudio output word lengths and sampling rates from 32kHzto 96kHz are supported.

The WM8738 is available in a small 14-pin SOIC package.
