LMV771/LMV772/LMV774

Single/Dual/Quad, Low Offset, Low Noise, RRO

Operational Amplifiers

General Description

Features

The LMV771/LMV772/LMV774 are Single, Dual, and Quad

low noise precision operational amplifiers intended for use in

a wide range of applications. Other important characteristics

of the family include extended operating temperature range,

−40˚C to 125˚C, tiny SC70-5 package for LMV771, and low

input bias current.

The LMV771/LMV772/LMV774 family is designed for preci-

sion, low noise, low voltage, and miniature systems. These

amplifiers provide rail-to-rail output swing into heavy loads.

The maximum input offset voltage for LMV771 is 850 µV at

room temperature and the input common mode voltage

range includes ground.
