What the LMV321IDCKRUMW family does
The UMW LMV321/LMV358/LMV324 are low-power, rail-to-rail input and output operational amplifiers available in single, dual, and quad configurations. These devices operate across a wide voltage range of 2.1V to 5.5V with a typical gain bandwidth product of 1MHz. They feature low input bias currents of 10nA and quiescent currents ranging from 45µA to 180µA depending on the variant. The family is typically used in battery-powered equipment, sensor interfaces, and audio output applications. Their wide input common-mode voltage and output swing make them suitable for portable stereo radio recorders and mobile communication systems.
