LMV844 - Quad CMOS Input, RRIO, Wide Supply Range Quad Operational Amplifiers

Updated : 2020-01-09 14:18:42
Description

The LMV84x devicesare low-voltage and low-power operational amplifiers that operate with supply voltages ranging from2.7 V to 12 V and have rail-to-rail input and output capability. Their low offset voltage, lowsupply current, and CMOS inputs make them ideal for high impedance sensor interface andbattery-powered applications.

The single LMV841 isoffered in the space-saving 5-pin SC70 package, the dual LMV842 in the 8-pin VSSOP and 8-pin SOIC packages, and the quadLMV844 in the 14-pin TSSOP and14-pin SOIC packages. These small packages are ideal solutions for area-constrained PCBs andportable electronics.
