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.

Features

n No frequency compensation required

n Short-circuit protection

n Wide common-mode and differential voltage ranges

n Low-power consumption

n 8-lead can and 8-lead mini DIP

n No latch up when input common mode range is

exceeded
