Low Noise, J-FET Input Operational Amplifiers

Download Datasheet

  • 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.
