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.
