3 Description
The LMV3xx A family includes single (LMV321A), dual (LMV358A), and quad-channel (LMV324A) lowvoltage (2.5V to 5.5V) operational amplifiers (op amps) with rail-to-rail output swing capabilities. These op amps provide a cost-effective solution for spaceconstrained applications such as large appliances, smoke detectors, and personal electronics where lowvoltage operation and high capacitive-load drive are required. The capacitive-load drive of the LMV3xx A family is 500p F, 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 (2.5V to 5.5V) with performance specifications similar to the LMV3xx devices.
The robust design of the LMV3xx A 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 LMV3xx A family is available in industry-standard packages such as SOIC, MSOP, SOT-23, and TSSOP packages.
