NJM2904
SINGLE-SUPPLY DUAL OPERATIONAL AMPLIFIER
■ GENERAL DESCRIPTION
The NJM2904 consists of two independent, high gain,
internally frequency compensated operation amplifiers, which
were designed specifically to operate from a single power
supply over a wide range of voltages. Operation from split
power supplies is also possible and the low power supply
current drain is independent of the magnitude of the power
supply voltage.
Application areas include transducer amplifiers, DC gain
blocks, and all the conventional op amp circuits, which now can
be more easily implemented in single power supply systems.
For example, the NJM2904 can be directly operated off of the
standard +5V power supply voltage, which is used in digital
systems and will easily provide the required interface electronics
without requiring the additional ±15V power supplies.

(note 1) Continuous short-circuits from output to GND is guaranteed only when V  15V.
(note 2) For supply voltage less than 32V, the absolute maximum input voltage is equal to the supply voltage.

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