Definition
Operational amplifiers (op-amps) are devices that amplify the difference between their two inputs by a large gain factor. They have five terminals, including power supply terminals, inverting and non-inverting inputs, and an output terminal.
Summary
Operational amplifiers are essential components in electronics, widely used for amplifying voltage signals. They can be configured in various ways, such as inverting and non-inverting amplifiers, to achieve different functionalities. Understanding the principles of feedback and gain calculation is crucial for designing effective op-amp circuits. In practical applications, op-amps are utilized in audio equipment, signal processing, and many other devices. By mastering the basics of operational amplifiers, learners can build a strong foundation for more advanced topics in electronics and signal processing, leading to innovative applications in technology.
