Operational Amplifiers

The LMV321, LMV358, and LMV324 are CMOS single, dual, and

quad low voltage operational amplifiers with rail−to−rail output

swing. These amplifiers are a cost−effective 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. Rail−to−Rail operation provides improved

signal−to−noise 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 low−side current−shunt measurements. The ultra small packages

allow for placement on the PCB in close proximity to the signal source

thereby reducing noise pickup.
