NJM072B/082B/072/082
DUAL J-FET INPUT OPERATIONAL AMPLIFIER
■
GENERAL DESCRIPTION
The NJM072B/082B & NJM072/082 are dual 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.
The NJM072/082 may cause oscillation in some
application like voltage follower.

NOTICE WHEN APPLICATION
Recommendable product
072/082 are the products in which the AC feature have been made much higher comparing to the products of 072B/082B which
are compatible with 072/082 type of other company’s products. Therefore, 072/082 are unstable in oscillation when the voltage
follower application, and it is recommendable to use the standard type 072B/082B when newly designed. Beside these
products, we have NJM2082 which is higher up in AC feature, yet stability in oscillation, and then the driving capacity to the load
at the output stage is made much higher in operation.
