3 Description
The LM290xLV family includes the dual LM2904LV
and quad LM2902LV 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 LM2904
and LM2902 in low-voltage applications that are
sensitive to cost. Some applications are large
appliances, smoke detectors, and personal
electronics. The LM290xLV devices supply better
performance than the LM290x 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 LM290xLV family an HBM specification for
a minimum of 2 kV.
The LM290xLV family is available in packages that
have industry standards. The packages include
SOIC, VSSOP, and TSSOP packages.
