The LMV3xxA family includes single - (LMV321A), dual - (LMV358A) , and quad-channel (LMV324A) low-voltage (2.5 V to 5.5 V) operational amplifiers (op amps) with rail-to-rail output swing capabilities. These op amps provide a cost-effective solution for space-constrained applications such as large appliances, smoke detectors, and personal electronics where low-voltage operation and high capacitive-load drive are required. The capacitive-load drive of the LMV3xxA family is 500 pF, and the resistive open-loop output impedance makes stabilization easier with much higher capacitive loads. These op amps are designed specifically for low-voltage operation (2.5 V to 5.5 V) with performance specifications similar to the LMV3xx devices.The robust design of the LMV3xxA family simplifies circuit design. The op amps feature unity-gain stability, an integrated RFI and EMI rejection filter, and no-phase reversal in overdrive conditions. The LMV3xxA family is available in industry-standard packages such as SOIC, MSOP, SOT-23, and TSSOP packages.
