24 Bit Stereo ADC
DESCRIPTION
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 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 device is available in a small 14-pin SOIC package.
