(ACTIVE) Dual General-Purpose Operational Amplifier


The MC1458 and MC1558 are dual general-purpose operational amplifiers, with each half electrically similar to the µA741, except that offset null capability is not provided.

The high-common-mode input voltage range and the absence of latch-up make these amplifiers ideal for voltage-follower applications. The devices are short-circuit protected and the internal frequency compensation ensures stability without external components.


  • Short-Circuit Protection
  • Wide Common-Mode and Differential Voltage Ranges
  • No Frequency Compensation Required
  • Low Power Consumption
  • No Latch-Up
  • Designed to Be Interchangeable With Motorola MC1558/MC1458 and Signetics S5558/N5558
