MC1458 双路通用运算放大器

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
