Where do operational amplifiers get their use? Amplification refers to the process of amplifying anything. The amplifier boosts the input current or voltage in order to enhance the signal present in the electrical circuit. An electronic gadget called an amplifier boosts a signal's voltage, current, or power. Wireless communications, broadcasting, and many types of audio equipment all employ amplifiers. An integrated circuit with the ability to amplify weak electric impulses is called an operational amplifier. There are two input pins and one output pin on an operational amplifier.The voltage difference between the two input pins is amplified and output by it as its primary function. In a circuit, they are typically employed to amplify weak electrical current. headphones, TVs, stereos, radios, and numerous additional products include an operational amplifier in their circuits
