Improvement of Cross-over Distortion
Equivalent circuit at the output stage
NJM2904,in its static state ( No in and output condition ) when
design,Q
U
being biassed by constant current ( break down
beam ) yet,Q
L
stays OFF.
While using with both power source mode,the cross-ove
distortion might occur instantly when Q
L
ON.
There might be cases when application for amplifier of audi
signals,not only distortion but also the apparent frequenc
bandwidth being narrowed remarkably.
It is adjustable especially when using both power sourc
mode,constantly to use with higher current on Q
U
than the load
current ( including feedback current ),and then connect th
pull-down resister R
P
at the part between output and GND pins.
