NJRC NJM2902M-TE1 Quad single-supply operational amplifier Datasheet

NJM2902
QUAD SINGLE-SUPPLY OPERATIONAL AMPLIFIER
■ GENERAL DESCRIPTION
The NJM2902 consists of four independent high-gain
operational amplifiers that are designed for single-supply
operation.
Operation from split power supplies is also possible and the low
power supply drain is independent of the magnitude of the power
supply voltage.
Used with a dual supply the circuit will operate over a wide
range of supply voltages. However, a large amount of crossover
distortion may occur with loads to ground. An external
current-sinking resistor to-VS will reduce crossover distortion.
There is no crossover distortion problem in single-supply
operation if the load is direct-coupled to ground.

■ APPLICATION
Improvement of Cross-over Distortion
Equivalent circuit at the output stage
NJM2902,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.
