57. Op Amp Basics Part 1

[@Jnglfvr]

At 27:55 I think you misinterpreted the meaning of differential input voltage. Based upon footnote 3 at 28:00 differential refers to IN+ with respect to IN-. If you put 15 V on IN+ and -15V on IN- the differential voltage would be exceeded (30V).

Man. You are videos are so useful! Thanks. KZbin doesn't make you justice.

[@roberthatten5184]

good job, very good information for the entry-level to the experienced electronic tech/engineer.

[@TheOffsetVolt]

Thank you. I gear it more towards the tech but hopefully anyone can find the info understandable and useful.

[@TomLeg]

You should touch up the slew-rate diagram ... the op amp cannot anticipate a drop in the input signal, it can only react to one.

[@Manticore1960]

I know I'm late to the party, but I've only just seen this video. I was going to make the same comment when I saw the slew rate diagram. Just as the op amp reacts to the leading edge, it reacts the same way to the falling edge. i.e. it will start to fall at the same time as the input falling edge falls, not before. The op amp cannot know when that falling edge will occur.

perhaps this will be the most easy to understand video in KZbin librery related to op-amp... u r the great instructor...❤❤ thank you

[@electronicssciencebysherry5050]

Am glad to help me with amplifiers thank u

[@avicohen3035]

Well explained. Easy to understand. Thank you for this film. I am discouraged to use an IC. Its too easy. It is detrimental to take the easy way. You learn much more, by doing it the hard way.

[@jeevankumard1069]

Really enjoyed this presentation... 👍👍👍

[@d.buchko4270]

Love the videos "The Offset Volt" Can you please make one on the Howland Current Pump?

[@hasanalattar9561]

31:00 the input bias max is 500nA while input offset max is 300nA .. how is that possible if its the average of two inputs biases

[@sussy1930]

Using a simulation software such as multi sim and others. Is it possible to have a null output when the inputs are grounded . I'm not really sure if the software op amps operate practically or ideally.

[@electronicssciencebysherry5050]

Thank u very much Sir, but I wd like to learn 4rom u more powerful amplifiers like( Peavy 2000 amplifier ) used in disco all it's design techniques.

[@PerchEagle]

I want to run it as signal amplifier how to do that I have tried many times but didn't talk with me?

[@rodhenderson690]

41:07...isn't that answer pi????

[@PeterMilanovski]

I had no idea that there is dual output Op Amps with inverting and non inverting outputs. I know that vacuum tubes have this ability and I have seen their implementation in audio amplifiers to obtain the push pull output but with solid state I generally see the use of an extra Op Amp to do the inverting for the push pull output stages... Now I'm on a mission to find out which Op Amps have this dual output...

[@johnbuthelezi2543]

Shame now you know

[@ohmedarick1]

Your explanation is clear as water. Enjoyed the theory with the data sheet. I always have problems reading does complicated data sheets. Of course I don't know much!!!. thank you!!

[@TheOffsetVolt]

Thank you, it is always nice to get positive feedback and know that you clarified some topic.

[@prateekmishra4661]

How the log amplifier can be tuned around to provide antilog function?.

[@TheOffsetVolt]

Thanks for watching - this will be a video I'll have to get to.

[@alibehrouz9833]

it was so useful thanks brother

[@TheOffsetVolt]

I am glad it helped - thanks for watching!

[@awesometech-ul8tp]

Thanks for all the work that went into this. I'd love to see a video covering how to select a better op-amp, eg, for a modern 5V single rail application. Using very old op-amps like 741 leads to student disappointment, as the Op Amp's performance and limitations restricts uses. Better to teach something more modern, so students can then practice their understanding by applying it to their own real world problem.
