How Do Op-Amps Work?

Support the channel! :)
/ theaudiophool
You may (or may not!) know the 'golden rules' for op-amps. A few simplifying rules that allow us to analyse many op-amp circuits with ease. But do you know WHY those rules work? What is going on inside an op-amp? Lets have a look!

This is the best explanation of op-amps i have ever seen!!

Super helpful, very happy I found this channel

I am late to this party, but thank you got sharing your knowledge, I'm on the verge of understanding some of it!

[@TheAudioPhool]

You're not late, we're only just getting started!!

I never really attempted to understand the inner workings of an op amp before, but you made it seem so approachable! A request for a future video. In what ways do real op amps differ from the ideal model? Both in terms of what's going on inside and how it affects its behavior in common application circuits. What parameters do I need to understand to select an appropriate op amp?

[@TheAudioPhool]

Will definitely do a video on just that!

I’m actually surprised this channel don’t have more traffic. It’s up there with “SimplyPut” in my book. Keep up your sharing and passion for electronics. I’ve learned lots from channels like these. It drives me to do the same. Thanks Bunches.

Phucking brilliant!

I understand how it works for AC case, but how it is possible that it amplifies also small DC voltage? Where is the clue which enables that?

[@challchull3000]

the internal circuit does not capacitor coupled , so DC signal works

When I replace Q7 pnp by npn with all necessary changes for R17 and R18 it does not work. Why???

[@thypnotist]

Having Harry Potter explain electronic circuits is strangely comforting

All clean over my head, looking to see how op amps work, none the wiser for watching this video.

Hey G would you make me a sandwich

[@TheAudioPhool]

no

OK, except grabbing the nose. It is not esthetical. The rest is very good.
