LOW-NOISE J-FET INPUT OPERATIONAL AMPLIFIERS
■ GENERAL DESCRIPTION
The NJM072C/082C/NJM074C/084C are JFET input
operational amplifiers. They feature low input bias and
offset currents, high input impedance and fast slew rate.
The low harmonic distortion and low noise make them
ideally suit for amplifiers with high fidelity and audio
amplifier applications.
In addition, the realization of a wide operating temperature
reaches by a new design.

(1) Differential voltage is the voltage difference between +INPUT and -INPUT.
(2) Input voltage is the voltage should be allowed to apply to the input terminal independent of the magnitude of V+.
The normal operation will establish when any input is within the Common Mode Input Voltage Range of electrical characteristics.
