3 Description

The LMV93x-N family (LMV931-N single, LMV932-N

High-Side Current Sense Amplifier

dual and LMV934-N quad) are low-voltage, low-

power operational amplifiers. The LMV93x-N family

operates from 1.8-V to 5.5-V supply voltages and

have rail-to-rail input and output. The input common-

mode voltage extends 200 mV beyond the supplies

which enables user enhanced functionality beyond

the supply voltage range. The output can swing rail-

to-rail unloaded and within 105 mV from the rail with

600-

Ω load at 1.8-V supply. The LMV93x-N devices

are optimized to work at 1.8 V, which make them

ideal for portable two-cell, battery-powered systems

and single-cell Li-Ion systems.
