Overview

The LMV321B/358B/324B series are CMOS dual, and quad RRIO op-amps with low offset, low power and stable high frequency response. They incorporate 3PEAK’s proprietary and patented design techniques to achieve very good AC performance with 1MHz bandwidth, 0.7V/μs slew rate and low distortion while drawing only 80μA of quiescent current per amplifier. The input common-mode voltage range extends 100mV beyond V– and V+, and the outputs swing rail-to-rail. The LMV321B/358B/324B family can be used as plug-in replacements for many commercially available op-amps to reduce power and improve input/output range and performance. 

The combination of features makes the LMV321B/358B/324B ideal choices for motor control and portable audio amplification, sound ports, and other consumer Audio. The LMV321B/358B/324B Op-amp is very stable, and it is capable of driving heavy capacitive loads such as those found in LCDs. The ability to swing rail-to-rail at the inputs and outputs enables designers to buffer CMOS DACs, ASICs, or other wide output swing devices in single-supply systems.
