An internal power supply anti-pop circuit
prevents audible clicks and pops from being
heard when the CODEC is powered on and
off. This function is accomplished by
delaying the charge/discharge of the VREF
capacitor. A value of C
cause a turn-on delay of roughly 3 seconds,
which will allow the power supplies to
stabilize before the CODEC outputs are
enabled. The recommended value of
C
30 seconds. The CODEC outputs are also
kept stable for the same amount of time at
power-off to allow the system to be
gracefully turned off. Setting the VAGRamp
bit speeds up the ramp rate by 10X
(degrading the anti-pop performance), for
easier production testing. Any external
component anti-pop circuit is unaffected by
the internal circuit.
