This application note describes the operation of these digital mixers. The application note also shows how the mixers can be configured based on the different use cases. The configurable mixers described in this application note are available in the following ADC, DAC, and Codec families:
The TAC devices have digital mixers on both recording and playback paths, whereas the TAA devices feature these mixers only on the recording path, and TAD devices feature the mixers only on the playback path.
