Differential amplifiers are electronic devices used to amplify the difference between two input signals while rejecting any common-mode signals that are present in both inputs. They are commonly used in audio amplifiers, instrumentation amplifiers, and operational amplifiers. Differential amplifiers are designed to provide high gain, high common-mode rejection ratio, and low noise. They are widely used in various applications such as signal processing, data acquisition, and control systems. With their ability to accurately amplify small signals, differential amplifiers are an essential component in many electronic systems.

Frequently Asked Questions (FAQs)
1. What is a differential amplifier used for?
Differential amplifiers are used mainly to suppress noise. Noise consists of typical differential noise and common-mode noise, of which the latter can easily be suppressed with an op-amp.
2. What is differential and difference amplifier?
A differential amplifier (also known as a difference amplifier or op-amp subtractor) is a type of electronic amplifier that amplifies the difference between two input voltages but suppresses any voltage common to the two inputs.
3. What is the difference between op-amp and differential amplifiers?
The main difference between differential amplifier and operational amplifier is that a differential amplifier is an amplifier that amplifies a voltage difference between its inputs, whereas an operational amplifier is, in fact, a type of differential amplifier with a large open-loop gain, a high input impedance and a ...
4. What are the types of differential amplifier?
Differential Amplifier Configurations They are: Dual input balanced output. Dual input unbalanced output. Single input balanced output.
