Explain operational amplifier in detail​

Answer 1

$\huge\sf\underline{\underline{\pink{Ꭺ}\orange{N}\blue{Տ}\red{Ꮤ}\green{Ꭼ}\purple{Ꭱ}}}$

➢ An operational amplifier is an integrated circuit that can amplify weak electric signals. An operational amplifier has two input pins and one output pin. Its basic role is to amplify and output the voltage difference between the two input pins.

➢ Operational amplifiers are linear devices that have all the properties required for nearly ideal DC amplification and are therefore used extensively in signal conditioning, filtering or to perform mathematical operations such as add, subtract, integration and differentiation.

➢ An operational amplifier (often op amp or opamp) is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output. ... By using negative feedback, the characteristics of an op-amp circuit, its gain, input and output impedance, bandwidth etc.
