Descriptions The KA4558 is a monolithic integrated circuit designed for dual operational amplifier. Parameter tracking over temperature range. Large common mode and differential voltage range. com KA4558 Dual Operational Amplifier Features Integrator, Differentiator, Summer, adder, Voltage follower, etc.W w w.But again remember that modern Op-Amps like OPA2134 will consume 2-4 times more current than RC4558. They are less priced and consume very low current but are reported to have some jitters (slow and sloppy) when it comes to quality. Also since the IC has same properties as LM741 all the circuits with LM741 can be replaced with a RC4558.īe advised that the 4558 Op-Amps belongs to the old 1485 Op-Amp series and does not have great specs compared to modern Op-Amps. You can also find some Geiger counter circuits and Audio amplifier or comparator circuits based on this IC. Because of these characteristics these ICs are commonly found inside DVD players and Guitar amplifiers. It also has internal frequency compensation and short circuit protection in-built and hence requires minimum number of components to be application ready. This Op-Amp does not have a latch-up problem and hence is ideal to be used in voltage follower applications. It has a high common mode Input Voltage of ☑4V hence the inverting and non-inverting pins can be driven upto this voltage provided they are less than the operating voltage. The RC4558 is a Dual package version of the commonly used LM741 Op-Amp, both the IC share the same electrical characteristics except for that there is no offset and null option in the RC4558 Op-Amp.
