Operational Amplifier Working Principle

An operational amplifier is an integrated circuit used to process electrical signals such as those in an analog-to-digital converter (ADC). It contains two independent but complementary transistors, one of which is non-inverting and the other inverting. The transistors are connected together through a differential input voltage, typically within the range of 1 to 5 V. The voltage fed to the non-inverting input will be smaller than the signal at the inverting input. The amplifier takes the difference of these two signals, amplifies it, and the output is like a controlling signal or voltage of the differential amplifier. An operational amplifier can be used as a voltage controlled gain amplifier, a unity gain buffer, or an active filter. The gain of the amplifier can be varied by manipulating its internal components.
