LMV321A
- Low input offset voltage: ±1mV
- Rail-to-rail output
- Unity-gain bandwidth: 1MHz
- Low broadband noise: 30nV/√ Hz
- Low input bias current: 10pA
- 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
The LMV3xxA family includes single (LMV321A), dual (LMV358A), and quad-channel (LMV324A) low-voltage (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 space-constrained applications such as large appliances, smoke detectors, and personal electronics where low-voltage operation and high capacitive-load drive are required. The capacitive-load drive of the LMV3xxA family 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 LMV3xxA 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 family is available in industry-standard packages such as SOIC, MSOP, SOT-23, and TSSOP packages.
