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-V
S
will reduce crossover distortion.
There is no crossover distortion problem in single-supply
operation if the load is direct-coupled to ground.

(Note1) Continuous short-circuits from output to GND is guaranteed only when V+≤15V.
(Note2) For supply voltage less than 32V[±16], the absolute maximum input voltage is equal to supply voltage.
