LMV321A
LMV321A is Low-Voltage Rail-to-Rail Output Operational Amplifier manufactured by Texas Instruments.
Features - Low input offset voltage: ±1m V - Rail-to-rail output - Unity-gain bandwidth: 1MHz - Low broadband noise: 30n V/√ Hz - Low input bias current: 10p A - Low quiescent current: 70µA/Ch - Unity-gain stable - Internal RFI and EMI filter - Operational at supply voltages as low as 2.5V - Easier to stabilize with higher capacitive load due to resistive open-loop output impedance - Extended temperature range: - 40°C to 125°C 2 Applications - Smoke detectors - Motion detectors - Wearable devices - Large and small appliances - EPOS - Barcode scanners - Sensor signal conditioning - Power modules - Personal electronics - Active filters - HVAC: heating, ventilating, and air conditioning - Motor control: AC induction - Low-side current sensing 3 Description The LMV3xx A family includes single (LMV321A), dual (LMV358A), and quad-channel (LMV324A) lowvoltage (2.5V to 5.5V) 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 LMV3xx A family is 500p F, 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 LMV3xx A 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 LMV3xx A family is available in industry-standard packages such as SOIC, MSOP, SOT-23, and TSSOP packages.
