DESCRIPTIONS
The LM4558 devices is a monolithic integrated circuit designed for dual operational amplifier.
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 compen
-sation ensures stability without external components.
The LM4558 is characterized for operation from 0oC TO 70oC.
