Product Summary
The WM8738ED/R 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 WM8738ED/R also has a selectable digital high pass filter to remove residual DC offsets. Stereo 24-bit multi-bit sigma delta ADCs are provided, along with oversampling digital interpolation filters. 24-bit digital audio output word lengths and sampling rates from 32kHz to 96kHz are supported. The WM8738ED/R is available in a small 14-pin SOIC package. Applications include CD and Minidisc Recorders, DVD Players and General Purpose Audio Conversion.
