LMV321A-Q1 Automotive Rail-to-Rail Output Op Amp

Texas Instruments' single-channel offset voltage amp is ideal for low-supply applications and driving sampling ADCs

Image of Texas Instruments' LMV321A-Q1 Automotive Rail-to-Rail Output Op AmpTexas Instruments' LMV321A-Q1 is a single low-voltage (2.5 V to 5.5 V) automotive operational amplifier (op amp) with rail-to-rail output swing capabilities. This op amp provides a cost-effective method for space-constrained applications such as infotainment and lighting where low-voltage operation and high capacitive-load drive are required. The capacitive-load drive is 500 pF and the resistive open-loop output impedance makes stabilization easier with much higher capacitive loads. The LMV321A-Q1 is designed for low-voltage operation (2.5 V to 5.5 V) with performance specifications similar to the LMV3xx-Q1 devices.

The device's robust design simplifies the circuit design. Additional features include unity-gain stability, an integrated RFI and EMI rejection filter, and no-phase reversal in overdrive conditions. The op amp is available in industry-standard packages such as SOIC, MSOP, SOT-23, and TSSOP.
