A few tips of my own: 1) "typ" specs are the ones they sent to someone else. Design using the worst case numbers 2) Remember that the output currents came from the supply connections ensure a low RF impedance on the supplies. 3) Almost all op-amp circuits are ruled by Ohm's law. You rarely need to memorize any other equation. 4) If a number is not given as a min or max in the data sheet presume that one is dreadful for the purpose of design 5) Don't limit your thinking based on examples you have seen (Supply voltages of -7V and +10V are fine for example)
Howdy. Nice. I would like to mention two more points. 1. Keep in mind there is always a small input leakage current. Provide this leakage to be drained not to upset the work point. (Caused a lot of headaches for me.) 2. For Hi-Fi. If half of the output swing suffices. Design the work point to be at about half the B+ or B- to avoid cross over distortion. (A hint i saw in another UA-cam clip.) Regards.
On #2, a resistor to the minus rail can be used to keep the op-amps output in class A. Rarely, however is any of this really needed because op-amps that are really good can be bought.
I had op amp ,lessons in college decades ago , your video taught me more for memory , than the college class . Thanks
Thank you for your kind words. I am so glad you found the video useful.

Yes, some really good ideas. I might need to do another video - a sequel!!

Yes, good ideas.
Awesome tips 👍
Glad you like them! Thanks for watching.
Thank you v much Sir, great value vedio.
You are most welcome. I'm glad you appreciated the video.
