Overview
The MC1458DRE4 is a dual general-purpose operational amplifier produced by Texas Instruments. It is part of the MC1458 series, which is electrically similar to the μA741, but without the offset null capability. This device is designed for a wide range of applications requiring high common-mode input voltage range and stability without external frequency compensation. The MC1458DRE4 is available in an 8-pin SOIC package and is RoHS compliant.
