NJU7076/NJU7077/NJU7078

Precision, Low Noise, Rail-to-Rail Output,

CMOS Operational Amplifier

■ GENERAL DESCRIPTION

■ PACKAGE OUTLINE

The NJU7076/NJU7077/NJU7078 is a high precision

Rail-to-Rail output Single/Dual/Quad CMOS operational

amplifier featuring a low noise of 10nV/√Hz typ., low input

offset voltage of 150µV max., low temperature drift of

0.5µV/°C typ. and low bias current of 1pA typ..

The output swing can reach 20 mV from the rails, while driving

a 10kΩ load (at 5V operation). The NJU7076/NJU7077/

NJU7078 also has a high RF noise immunity which can

reduce malfunctions caused by RF noises from mobile

phones and others. The combination of these specifications

makes the NJU7076/ NJU7077/NJU7078 well-suited for

sensor applications such as a temperature sensor, weight

sensor and others, high precision current sensing amplifiers

and current voltage converters.
