General Description

The

LMV321 family have a high gain-bandwidth product of 1MHz, a slew rate of 0.6V/μs, and a quiescent current of 40μ

A/amplifier at 5V. The

LMV321 family is designed to provide optimal performance in low voltage and low noise systems. They

provide rail-to-rail output swing into heavy loads. The input common mode voltage range includes ground, and the maximum

input offset voltage is 3.5mV for

LMV321 family. They are specified over the extended industrial temperature range (-40℃ to

+125

℃). The operating range is from 2.1V to 5.5V. The LMV321 single is available in Green SC70-5 and SOT-23-5 packages.

The

LMV358 Dual is available in Green SOP-8, MSOP-8, DIP-8 and DFN-8 packages. The LMV324 Quad is available in Green

SOP-14 and TSSOP-14 packages.
