LMV841 / LMV844

CMOS Input, RRIO, Wide Supply Range Operational

Amplifiers

General Description

The LMV841 and LMV844 are low-voltage and low-power

operational amplifiers that operate with supply voltages rang-

ing from 2.7V to 12V and have rail-to-rail input and output

capability.

The LMV841 and LMV844 are low offset voltage and low

supply current amplifiers with MOS inputs, characteristics that

make the LMV841/LMV844 ideal for sensor interface and

battery powered applications.

The LMV841 is offered in the space saving 5-pin SC70 pack-

age and the quad LMV844 comes in the 14-Pin TSSOP

package. These small packages are solutions for area con-

strained PC boards and portable electronics.
