LM1558/LM1458 Dual Operational Amplifier
April 1998
LM1558/LM1458
Dual Operational Amplifier
General Description
The LM1558 and the LM1458 are general purpose dual op-
erational amplifiers. The two amplifiers share a common bias
network and power supply leads. Otherwise, their operation
is completely independent.
The LM1458 is identical to the LM1558 except that the
LM1458 has its specifications guaranteed over the tempera-
ture range from 0˚C to +70˚C instead of −55˚C to +125˚C.
