F
To eliminate DC
Cut-off frequency is
increased
Cut-off frequency is reduced
Pop noise is
generated when
VCC is ON
C2
10
F
To reduce ripple
Powering ON/OFF is faster
Powering ON/OFF takes
longer
C3
0.1
F
To provide
sufficient
oscillation margin
Reduces noise and provides sufficient oscillation margin
C4
1
F
To reduce pop
noise
High pop noise. Duration until
muting function is turned
ON/OFF is short
Low pop noise. Duration until
muting function is turned
ON/OFF is long
C5
3900
F
Ripple filter
Power supply ripple filtering
C6
1
F
NF for all outputs
Pop noise is suppressed when C1:C6
= 1:4
Pop noise is
generated when
VCC is ON
Note6: If recommended value is not used.
