Op-amp Basics (part 1): Operational amplifiers (op-amps) are some of the most important, widely used, and versatile circuits in use today. The first op-amp used vacuum tubes and was released in 1941 by Bell Labs. The ubiquitous ua741 was released in 1968
Ideally, we would want the op amp to present minimum loading effects so we want a high input impedance. It is important to remember that an ideal op amp has infinite input impedance. This means that the driving circuit does not have to supply any current to the op amp. Another way to ...
