3 Description

The LMV3xxA 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 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.
