Here you will learn about operational amplifier basics concept, how it works and it’s types. An operational amplifier is a DC-coupled high-gain electronic voltage amplifier that has high gain, differential input, high input resistance, and low output resistance.
It produces an output potential (without feedback) which is typically hundreds of thousands of times larger than the differential input voltage. That’s why it is mostly present in electronics circuits. Operational amplifiers are also called OP-AMP.
To understand operational amplifier’s working you must read about operational amplifier basics
There are two configurations for the operational amplifier
1-inverting OP-AMP
2-non-inverting OP-AM
A non-inverting amplifier is an OPAMP circuit configuration whose output is in phase with the input signal at the non-inverting input. The input signal is applied at the non-inverting input of the opamp. A non-inverting amplifier also acts as a voltage follower circuit. The non-inverting amplifiers also have negative feedback which is used to control […]
The inverting amplifier is one of the types of closed loop opamp configuration. In this configuration, the non-inverting (+ve) terminal of the opamp is connected to the ground, while the inverting terminal acts as input terminal. Negative feedback is present between the output terminal and (-ve) inverting terminal of OPAMP. Importance of negative feedback in Inverting […]
Let’s see IC OP AMP IC 741 Pin Diagram and working with its applications operational amplifier IC 741 is one of the oldest and most popular IC with high performance. It’s been around since the 1960s and is still used in various applications today. The “741” refers to the model number assigned by the manufacturer, […]
