1 tWAIT MIN and tHOLD MIN are the minimum times for fast turn-on and do not guarantee pop-and-click suppression.
2 tWAIT TYP is the recommended value for minimum pop and click during the unmute of the amplifier. The recommended value is 1 sec. It is calculated using the input
coupling capacitor value and the input resistance of the device. See the Power-Up/Power-Down Sequence section.
3 tHOLD TYP is the recommended value for minimum pop and click during the mute of the amplifier.
