It could prevent pop noise effectively when power on and power off. The signals of power down function (pin5) and mute function (pin13) are ignored during initial time 350ms when power on. It is better to control mute function after 1sec. The sequence is mute on and then power down when power off. POWER PD Power on: Delay >350msec from power on to mute off. Power off: Delay >0sec from mute on to power off. 350ms 1sec >0sec VTM Voutput Fig.3 Power and mute function timing.
