7.4.7 Analog Audio Routing

The TAS2505 has the capability to route the DAC output to the speaker output. If desirable, both output drivers can be operated at the same time while playing at different volume levels. The TAS2505 provides various digital routing capabilities, allowing digital mixing or even channel swapping in the digital domain. All analog outputs other than the selected ones can be powered down for optimal power consumption.

For more detailed information see the TAS2505 Application Reference Guide (SLAU472).
