Low Offset, Low Drift single JFET Input

Operational Amplifier

■GENERAL DESCRIPTION

■PACKAGE OUTLINE

The NJM2748/2748A is a Precision dual JFET input operational

amplifier which includes low input offset voltage: 0.7mV (typ) / 2.0mV

(max) and 6µV/°C typical offset drift.

The NJM2748A is guaranteed 20µV/°C maximum offset drift to

perform a 100% tested.

The NJM2748/2748A have the following features: low bias current of

50pA (typ), high slew rate of 13V/µs (typ).

These features are suitable for signal processing amplifiers of

instrumentation, measurement and industrial applications such as

sensor amplifier, current sensing and sample-and-hold circuit.
