Description
In this lesson, we'll dive into the world of operational amplifiers (op-amps) and explore their significance in electronic circuits. We'll start by discussing the origins of op-amps and how they were used in analog computers before digital computers became popular. Then, we'll delve into the key features of op-amps, such as their ability to perform addition and sign change, and scale signals. Along the way, we'll cover important topics like voltage and current gain, input and output stages, and common applications of op-amps in circuits. By the end of this lesson, you'll have a solid understanding of op-amps and their importance in electronic engineering.
