Main Question or Discussion Point
Can Op Amps replace transistors? Can they do everything a transistor does? They can be used as comparators and amplifiers. Will they become obsolete.
I always had that problem myself but I was confused by your asking if they can do everything a transistor can do. An op amp is WAY more complex than a single transistor. It's a controlled voltage source with a feedback look. It has many transistors in it. No, I don't think they will become obsolete, although you never know what the future will hold.I have taken courses. I just seem to have trouble using Op Amps in circuits, or getting what's going on with its inputs and outputs when they are connected to other components.
You are asking extremely broad questions. You really need to study circuit analysis and play with them in the lab (or possibly in a simulator). Asking shotgun questions on an internet forum is not the best way to learn this stuff.How do I use inductors and capacitors to enhance the op amp? What effect do those components have in the circuit?
You are "shamed" only if you choose to be. What I pointed out was NOT about the fact that you don't know how an op amp works but about the fact that you are asking questions that are so basic as to make clear that you have not done any research on your own.I play a part in the development of high-tech products. I don't know how an op amp works or how to use it. I'm so shamed? Did Steve Jobs know how to use op amps when he invented the iPhone?
Please see what you can find out on your own and send me a message with the result if you have more specific follow-up questions, then I will open the thread again.Do op amps go good with motors?
