An operational amplifier, often referred to as an op-amp, is a type of electronic amplifier that is commonly used in analog circuits. It has two input terminals, an inverting (-) and a non-inverting (+) terminal, and one output terminal. The op-amp amplifies the voltage difference between the two input terminals and produces an output voltage that is proportional to this difference.
Op-amps are used in a wide range of applications, including signal conditioning, filtering, amplification, and mathematical operations. They are typically used in conjunction with other components such as resistors, capacitors, and feedback networks to create complex analog circuits.
Op-amps have high input impedance, low output impedance, and high gain, making them versatile and widely used in electronic circuits. They are available in various configurations, such as single, dual, and quad op-amps, and come in different packages such as DIP, SOIC, and SMD.

Operational amplifier (op-amp)
An operational amplifier is a high-gain electronic amplifier with a differential input and, usually, a single-ended output. Operational amplifiers are used as building blocks in a wide range of electronic circuits such as amplifiers, filters, and oscillators.
Description
- High gain: Op-amps have a very high open-loop gain, typically 100 dB or more. This means that even a small difference in the input voltage will result in a large change in the output voltage.
- Differential input: Op-amps have two input terminals, called the inverting input (-) and the non-inverting input (+). The output voltage is determined by the difference between the voltages at these two inputs.
- Single-ended output: Op-amps have a single output terminal. The output voltage is referenced to the ground terminal.
- Feedback: Op-amps are often used in feedback configurations. Negative feedback reduces the gain of the amplifier and improves its stability. Positive feedback can be used to create oscillators and other types of circuits.
Applications
Op-amps are used in a wide range of electronic circuits, including:
- Amplifiers
- Filters
- Oscillators
- Comparators
- A/D and D/A converters
- Signal conditioning circuits
- Instrumentation amplifiers
- Power amplifiers
Types of op-amps
There are many different types of op-amps available, each with its own unique characteristics. Some of the most common types include:
- General-purpose op-amps: These are the most common type of op-amp and are suitable for a wide range of applications.
- High-speed op-amps: These op-amps have a higher gain-bandwidth product than general-purpose op-amps and are suitable for high-frequency applications.
- Low-power op-amps: These op-amps consume less power than general-purpose op-amps and are suitable for battery-powered applications.
- Rail-to-rail op-amps: These op-amps have an output voltage that can swing all the way to the positive and negative power supply rails.
Conclusion
Operational amplifiers are a versatile and powerful electronic component that can be used to build a wide range of circuits. Their high gain, differential input, and single-ended output make them ideal for a variety of applications, including amplifiers, filters, and oscillators.
