LM1558/LM1458 Dual Operational Amplifier
General Description
The LM1558andthe LM1458are general purpose dualop-
erational amplifiers. The two amplifiers sharea common
bias networkand power supply leads. Otherwise, their oper-
ationis completely independent.
The LM1458is identicaltothe LM1558 except thatthe
LM1458hasits specifications guaranteedover thetempera-
ture range from 0§Cto a70§C insteadof b55§Cto
a125§C.
FeaturesNo frequency compensation required Short-circuit protection Wide common-mode and differential voltage ranges Low-power consumption 8-leadcanand 8-lead miniDIPNo latchup when input common mode rangeis
exceeded
