Good video and nice presentation with demos. I recommend Arthur Kay's book about Op Amp Noise for practical engineers. However, I think we miss a very important part of op amp topic, which is the modeling of the op amp. Think about modeling of the noise sources, CMRR, PSRR, slew rate, input impedance, and output impedance.

This is fantastic video. I have learnt many by this video. Thank you❤

Great video! One request Make this kind of video for every circuit element. That would be great

@RobertFeranec Ай бұрын

thank you. this is on my todo list. the hard part is finding people. so if anyone knows some very good engineers who would like to talk about these topics, please send me an email or message on linked in.

A lot of useful information in this video Robert. Must watch before dealing with op amps. I'm just in the process for selecting proper op amps for my electronic load(i think i'm choosing opa189).

That's some high quality content and perfect to complement my reading of Chapter 4 of Art of Electronics

OPA928 is a competative of the long out-standing ADA4530-1, which appeared roughly in 2016. And TI even made it pin to pin compatible to ADA4530-1, with the same guard ring structure.

Thanks! It was pretty theoretical right from university, I don't know something is missing. The part of stability was nice (don't put capacitor directly to opamp output) and for guarding. I think I am missing some practical solutions for low voltage signals. ECG, Potentiostat, Strain Gauge. These are pretty common applications where you can describe small lifehacks and tradeoffs with opamps regarding their parameters schematic and layout.

And maybe for this I would ask AD guys (sorry TI you are good for high power)

@RobertFeranec Ай бұрын

Thx. Please do you have any contacts in AD?

@sXAPOLLls Ай бұрын

@@RobertFeranecI have, but I am not sure they are better than yours =) As HW engineer I work not with best lectors, but with other engineers. Also with AD there is a problem, once you get to something interesting they force you to sign NDA. No offense Robert, You do your best. It is because usually you provide something mindblowing this one didn't really catch me.

@@RobertFeranec Also Robert, in TI they recently introduced pretty interesting LED driver LP5813. It is matrix, with Autonomous (no need constant I2C polling), integrated high efficient boost, 0.1uA sleep, small like 2x3mm and cost 0.3USD. I start putting this driver any battery operated project.

Everything thing about op-amps is mathematics related, its invention by design was for a analog computers part #741, so the first topic out the door is DC again and DC feedback, advance topics are AC parameters this is where we enter the upside down world TYPE-1,2 and 3 compensators and beyond.

Nice informative

Can we download the presentation somewhere?

HI Robert, I am currently working on projects involving the design of electronic circuits for Atex products. Would it be possible for you to create a video addressing this specific topic? I am confident that your expertise would be of great help to me and others in the field.
