Texas Instruments LMV3xxA/LMV3xxA-Q1 Low-Voltage Op Amplifiers

Texas Instruments LMV3xxA/LMV3xxA-Q1 Low-Voltage Operational Amplifiers (Op Amps) are low-voltage (2.5V to 5.5V) op amps with rail-to-rail output swing capabilities. These op amps provide a cost-effective solution for space-constrained applications. These applications include large appliances, smoke detectors, and personal electronics, requiring low-voltage operation and high capacitive-load drive. The capacitive-load drive of the LMV3xxA is 500pF, 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 Texas Instruments LMV3xxA simplifies the circuit design. The op amps feature unity-gain stability, an integrated RFI and EMI rejection filter, and no-phase reversal in overdrive conditions.
