One of the most important functions of electronic circuitry is amplification. In the absence of amplification, many other specific circuits would not work.
The MC1436 is a summing amplifier, integrator, or amplifier with operating characteristics as a function of the external feedback components. The supply voltage of LM201 is ±30V.
LM4558 is an IC consists of Two General Purpose Operational Amplifiers and is a member of ‘LMxx’ family. The LM series originated with integrated circuits made by National Semiconductor.
