3 Description

The LM3xxLV family includes the single LM321LV,

dual LM358LV, and quad LM324LV operational

amplifiers, or op amps. The devices operate from a

low voltage of 2.7 V to 5.5 V.

These op amps supply an alternative to the LM321,

LM358, and LM324 in low-voltage applications

that are sensitive to cost. Some applications are

large appliances, smoke detectors, and personal

electronics. The LM3xxLV devices supply better

performance than the LM3xx devices at low voltage,

and have lower power consumption. The op amps are

stable at unity gain, and do not have reverse phase

in overdrive conditions. The design for ESD gives the

LM3xxLV family an HBM specification for a minimum

of 2 kV.

The LM3xxLV family is available in packages that

have industry standards. The packages include

SOT-23, SOIC, VSSOP, and TSSOP packages.
