With inadequate system design, the TAS576xM can exhibit pop on power down. Pops are caused by the device not having enough time to detect power loss and start the muting process.
The TAS576xM evaluation board avoids audible pop with an electrolytic decoupling capacitor. This capacitor provides enough time between data loss from USB or S/PDIF and power supply loss for the muting process to take place.
The TAS576xM has two auto-mute functions to mute the device upon power loss (intentional or unintentional).
