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.
