LMV321A - Single Low-Voltage, Cost-Optimized Rail-to-Rail Output Operational Amplifier

The LMV3xxA familyincludes 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 outputswing capabilities. These op amps provide a cost-effective solution for space-constrainedapplications such as large appliances, smoke detectors, and personalelectronics where low-voltage operation and high capacitive-load drive are required. Thecapacitive-load drive of the LMV3xxA family is 500 pF, and the resistive open-loop output impedancemakes stabilization easier with much higher capacitive loads. These op amps are designedspecifically for low-voltage operation (2.5 V to 5.5 V) with performance specifications similar to theLMV3xx devices.

The robust design of the LMV3xxA family simplifies circuit design. The op amps feature unity-gainstability, an integrated RFI and EMI rejection filter, and no-phase reversal in overdriveconditions.

The LMV3xxAfamily is available in industry-standard packages such as SOIC, MSOP, SOT-23 and TSSOPpackages.
