Op Amp (Operational Amplifier)

An operational amplifier (op-amp) is a versatile electronic device that boosts the difference in voltage between two input points. Think of it as a highly sensitive amplifier that takes a small electrical signal and makes it larger, enabling precise control and measurement in electronic systems. Op-amps are used in various applications like audio amplification, filtering signals, and creating mathematical functions (like addition or integration) in circuits. They are fundamental building blocks in modern electronics, working behind the scenes to process and manipulate electrical signals efficiently.
