11. Application Supplements
11.1. Standby Mode
In standby mode the ALC892 turns on DC bias on all analog input and output ports (NID=14h~1Bh).
This is a special application to avoid ‘Pop’ noise while the system is in power on and power off transition
stages.
Table 88 shows the DC bias state when Standby mode is enabled.
