Section Five Function Introduction to IC
3.5.1 function introduction to 4558
1. Description
The RC4558 and RM4558 devices are dual general-purpose operational amplifiers with each half
electrically similar to the
A741 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.
The RC4558 is characterized for operation from 0
C to 70
C, and the RM4558 is characterized for
?
?
operation over the full military temperature range of –55 C to 125 C.
