To eliminate DC
To reduce ripple
To provide
sufficient
oscillation margin
To reduce pop
noise
Ripple filter
NF for all outputs
Purpose
Cut-off frequency is
increased
Powering ON/OFF is faster
Reduces noise and provides sufficient oscillation margin
High pop noise. Duration until
muting function is turned
ON/OFF is short
Power supply ripple filtering
Pop noise is suppressed when C1:C6 = 1:4
Lower than recommended
6
value
Effect
Cut-off frequency is reduced
Powering ON/OFF takes
longer
Low pop noise. Duration until
muting function is turned
ON/OFF is long
Higher than recommended
