Low-Voltage, Rail-to-Rail
Operational Amplifiers
The LMV321, LMV358, and LMV324 are CMOS single, dual, and
quad low voltage operational amplifiers with railâtoârail output
swing. These amplifiers are a costâeffective solution for applications
where low power consumption and space saving packages are critical.
Specification tables are provided for operation from power supply
voltages at 2.7 V and 5 V. RailâtoâRail operation provides improved
signalâtoânoise preformance. Ultra low quiescent current makes this
series of amplifiers ideal for portable, battery operated equipment. The
common mode input range includes ground making the device useful
for lowâside currentâshunt measurements. The ultra small packages
allow for placement on the PCB in close proximity to the signal source
thereby reducing noise pickup.
