Once the driver DC bias has reached VDD/2 and the
transient on the switch side of the DC blocking capacitor
has been discharged to ground through the click/pop
shunt circuitry, the audio switches can be turned ON and
connected through to the speaker loads without
generating any undesirable click/pop noise in the
speakers.

With a typical DC blocking capacitor of 220µF and the
click/pop shunt circuitry designed to have a resistance
of 20Ω to 70Ω, allowing a 100ms wait time to discharge
the transient before placing the switch in the Audio
mode will prevent the transient from getting through
to the speaker load. See Figures 30 and 31 in the
“Typical Performance Curves” section.
