Mono CODEC with Speaker Driver
DESCRIPTION
The WM8940 is a low power, high quality mono CODEC designed for portable applications such as digital still cameras or camcorders.
The device integrates support for a differential or single ended mic, and includes drivers for speakers or headphone, and mono line output.

A selectable high pass filter and four fully-programmable notch filters are available in the ADC path.
