Operational Amplifier

Operational Amplifiers are basically voltage amplifying devices designed to be used with components like capacitors and resistors. They serve as the core part of any analog device. Feedback components like capacitors and resistors are used to determine the operation of the amplifier. The amplifier can perform many different operations (resistive, capacitive, or both), giving it the name Operational Amplifier. Op-amps are linear devices that are ideal for DC amplification and are used often in signal conditioning, filtering or other mathematical operations
