LMV321AUQDBVRQ1

The LMV3xxA-Q1 family includes single (LMV321AQ1), dual (LMV358A-Q1), and quad-channel (LMV324A-Q1) low-voltage (2.5 V to 5.5 V) automotive operational amplifiers (op amps) with rail-to-rail output swing capabilities. These op amps provide 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 of the LMV3xxA-Q1 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-Q1 devices. The robust design of the LMV3xxA-Q1 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 LMV3xxA-Q1 family is available in industry-standard packages such as SOIC, MSOP, SOT-23, and TSSOP packages.
