Overview
The MC1458P is a dual general-purpose operational amplifier produced by Texas Instruments. Each half of the MC1458 is electrically similar to the µA741, except that it does not provide offset null capability. This operational amplifier is designed for a wide range of applications due to its high-common-mode input voltage range, absence of latch-up, and internal frequency compensation, which ensures stability without the need for external components.
