LMV841/LMV842/LMV844
CMOS Input, RRIO, Wide Supply Range Operational
Amplifiers
General Description
The LMV841/LMV842/LMV844 are low-voltage and low-pow-
er operational amplifiers that operate with supply voltages
ranging from 2.7V to 12V and have rail-to-rail input and output
capability. Their low offset voltage, low supply current, and
MOS inputs make them ideal for sensor interface and battery-
powered applications.
The single LMV841 is offered in the space-saving 5-Pin SC70
package, the dual LMV842 in the 8-Pin MSOP and 8-Pin
SOIC packages, and the quad LMV844 in the 14-Pin TSSOP
and 14-Pin SOIC packages. These small packages are ideal
solutions for area-constrained PC boards and portable elec-
tronics.
