RC4558 Dual General Purpose Op-Amp

Contents hide

RC4558 IC is a dual general-purpose operational amplifier, with each half electrically similar to the μA741, except that offset null capability is not provided. The IC has a range of working conditions a wide range of working voltages and possesses direct interfacing capability with almost every PMOS, CMOS, and NMOS device. Moreover, the IC offers a wide array of features such as high noise immunity, ESD barring/reduction, and exceptionally low power dissipation.

Operational Amplifier

Operational Amplifiers are basically voltage amplifying devices designed to be used with components like capacitors and resistors. They serve as the core part of any analog device. Feedback components like capacitors and resistors are used to determine the operation of the amplifier. The amplifier can perform many different operations (resistive, capacitive, or both), giving it the name Operational Amplifier. Op-amps are linear devices that are ideal for DC amplification and are used often in signal conditioning, filtering or other mathematical operations. There are are two main classifications of op-amps

Inverting
Non – inverting
