LMV841

CMOS Input, RRIO, Wide Supply Range Operational

Amplifier

General Description

The LMV841 is a low-voltage and low-power operational am-

plifier that operates from supply voltages from 2.7V to 12V

and has rail-to-rail input and output capability.

The LMV841 is a low offset voltage and low supply current

amplifier with MOS inputs, characteristics that make the

LMV841 ideal for sensor interface and battery powered ap-

plications.
