OPERATIONAL AMPLIFIER APPLICATIONS A high-gain, the direct-coupled amplifier is what an operational amplifier is. It has two inputs and an output, but generally, it is operated in single-ended input - single-ended output mode. Op-amp can perform several arithmetic operations like addition, subtraction, differentiation, integration, comparison, analog to digital conversion, etc. Op-amps are used in analog computers. IC 741 is a widely used OP-Amp. In this IC when the input is zero, the output can be adjusted to zero by varying the 10kΩ potentiometer between ‘offset null’ terminals. Applications of OP-Amp : There are many applications of Op-amp. It has a high open-loop gain, high input impedance, and low output impedance. It has a common-mode rejection ratio. Due to these favorable characteristics, it is used for different applications. Important Linear applications are- buffer, inverter, adder, and subtractor. Important non-linea...
