Operational Amplifier, Low Power, Rail to Rail Output, CMOS Op-Amp

Favorite

Overview

The LMV321/NCV321, LMV358, and LMV324 are single, dual, and quad low voltage op-amps 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 allows for optimal signal-to-noise applications. 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.
