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.
