The WM8352 contains a high-performance stereo DAC to convert digital audio signals to the
analogue domain. Audio data is passed to the WM8352 via the audio interface, and passes through
a variety of digital filtering stages before reaching the DAC. These include:
The audio DAC supports all commonly used audio sampling rates between 8kHz and 48kHz.
