آی سی LM4558C یک آپ امپ ( تقویت کننده عملیاتی ) دوبل می باشد.
The LM4558 devices are 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 compensation ensures stability without external components. The LM4558 is characterized for operation from 0oC TO 70oC.
