| 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.

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. -2- Ver.2003-03-17 NJM072B/082B/072/082 TYPICAL CHARACTERISTICS Ver.2003-03-17 -3- NJM072B/082B/072/082 -4- Ver.2003-03-17 NJM072B/082B/072/082 [CAUTION] The specifications on this databook are only given for information, without any guarantee as regards either mistakes or omissions.
