The WM8738 is a high performance stereo audio ADC designed for consumer applications. Stereo line-level audio inputs are provided, along with a control input pin to allow operation of the audio interface in either one of two industry standard modes. The device also has a selectable digital high pass filter to remove residual DC offsets. Stereo 24-bit multi-bit Delta Sigma ADCs are provided, along with oversampling digital interpolation filters. 24-bit digital audio output word lengths and sampling rates from 8 kHz to 96 kHz are supported. The device is available in a small 14-pin SOIC package.
