The LMV321, LMV358, and LMV324/LMV324S aresingle, dual, and quad low-voltage (2.7 V to 5.5 V)operaTIonal amplifiers with rail-to-rail output swing.The LMV324S, which is a variaTIon of the standardLMV324, includes a power-saving shutdown featurethat reduces supply current to a maximum of 5 μAper channel when the amplifiers are not needed.Channels 1 and 2 together are put in shutdown, asare channels 3 and 4. While in shutdown, the outputsacTIvely are pulled low.The LMV321, LMV358, LMV324, and LMV324S arethe most cost-effecTIve solutions for applicationswhere low-voltage operation, space saving, and lowcost are needed. These amplifiers are designedspecifically for low-voltage (2.7 V to 5 V) operation,with performance specifications meeting or exceedingthe LM358 and LM324 devices that operate from 5 Vto 30 V. Additional features of the LMV3xx devicesare a common-mode input voltage range thatincludes ground, 1-MHz unity-gain bandwidth, and1-V/μs slew rate.The LMV321 is available in the ultra-small DCK(SC-70) package, which is approximately one-half thesize of the DBV (SOT-23) package. This packagesaves space on printed circuit boards and enablesthe design of small portable electronic devices. It alsoallows the designer to place the device closer to thesignal source to reduce noise pickup and increasesignal integrity.
