LMV324AIDR

The LMV3xxA family includes single - (LMV321A), dual - (LMV358A), and quad-channel (LMV324A) lowvoltage (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 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 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.
