This is a very advanced and programmable ADC with additional support for I2S and SPI. The I2S is superflous, because a separate I2s module is used. But by using the I2s in this module, different features can be performed (Changing Bit Order). There is also a simplier A/D D/A module for other audio functionality.

| FFF93400 - FFF934FF | DAC |
This is a multi-functional Digital to Analog controller. It reduces noise and clock jitter based on its advanced algorithm engine.
