About Differential Amplifiers

Texas Instruments Differential Amplifiers

Differential amplifiers are amplifiers that use two inputs; the difference between them is amplified. Differential amplifiers are used in a variety of applications, such as switching and voltage regulation. They are also used in analog-to-digital conversion circuits and in instrumentation circuits. A differential amplifier is composed of two transistors. The current flowing through one transistor is proportional to the difference between the two input signals. The output voltage is then the difference between the two input signals multiplied by the gain of the amplifier. Differential amplifiers provide several advantages over single-ended amplifiers. They are more immune to common-mode noise, which is noise present on both inputs, and they can provide more linear amplification. Additionally, they can be used to amplify signals with low input impedance. Differential amplifiers can be used in many types of applications, depending on the requirements of the application. For example, they can be used in precision amplifiers, audio amplifiers, servo amplifiers, and stability amplifiers.
