Operational Amplifiers (Op Amps)

Operational amplifiers, or op-amps for short, are electronic circuits that provide a high gain amplification of an input voltage signal. They are widely used in electronic circuits for various signal processing tasks due to their versatile nature and high gain characteristics.

An op-amp typically has two input terminals (inverting and non-inverting), an output terminal, and a power supply. The output voltage of the op-amp is proportional to the difference between the voltages at the two input terminals, with the exact gain being determined by the circuit design.

Op-amps can be used in a variety of electronic circuits such as filters, amplifiers, oscillators, and voltage regulators. They can also be used as comparators, with the output switching to one of two voltage levels depending on the relationship between the two input voltages.

One of the main advantages of op-amps is that they can provide a very high gain, making them useful in amplifying small signals or reducing noise. They also have a wide range of input and output impedance, making them compatible with a wide range of electronic circuits. Additionally, op-amps can be designed to have very high input impedance, which means they can detect and amplify signals with minimal loading effects on the circuit they are connected to.
