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.
Features
3.0 -5.5V analog supply operation
3.0 -3.6V digital supply operation
ADC sampling frequency: 32 kHz - 96 kHz
selectable ADC high pass filter
selectable audio data interface modes
I²S or left justified
14-pin SOIC package
