Operation Amplifier |Op amp| Explanation in tamil

An operational amplifier is an integrated circuit that can amplify weak electric signals.
An operational amplifier has two input pins and one output pin. Its basic role is to amplify and output the voltage difference between the two input pins.

What an Operational Amplifier Can Do
An operational amplifier is not used alone but is designed to be connected to other circuits to perform a great variety of operations. This article provides some typical examples of usage of circuits with operational amplifiers.

When an operational amplifier is combined with an amplification circuit, it can amplify weak signals to strong signals.It behaves like a megaphone where the input signal is a person’s voice and the megaphone is the operational amplifier circuit.For example, such a circuit can be used to amplify minute sensor signals.

Processing of sensor signals can be further improved by inputting the amplified signal to a microcontroller* unit (MCU).
Microcontroller… A compact computer for controlling electronic devices. As the brain of electronic devices, MCUs operate according to input signals.
