From Forum members:

26  RSD Academy
http://www.youtube.com/channel/UCOausWDNRDJikQ11gSLj7nA/search?query=op+amp


I downloaded over 2,000 videos and combined them into the same folder to get rid of duplicates.  About 1,100 were left.  Then I went through them and deleted those that did not have "op amp" in the title.  Then there were 474 left.  I watched all 474 of them.  Took about 2 weeks.

Scoring method used, for detailed results see attached sheet:

Num of videos              Views                   Likes                        > 10 min      Score
' 1 = 1                      <1k = 1                    < 85% = 1          No = 1      
' 2 – 5 = 2                      '1k- 50k = 2         85 – 95% = 2         
' >5 = 3                       > 50k = 3            > 95% = 3           Yes = 3

Used this method of ranking:

Num of videos             Views                      Likes                        > 10 min      
' 1 = 1                     <1k = 1                     < 85% = 1                No = 1         
' 2 – 5 = 2                 '1k- 50k = 2              85 – 95% = 2            
' >5 = 3                      > 50k = 3              > 95% = 3                Yes = 3   

Drum roll please ..................................................

Just wanted to say that different people have different ways of learning. In my case I find w2aew's style to be the best to understand concepts that I do not fully grasp yet. So, people, just watch all these videos, not just the gold medalist. :)

But kudos for sticking to a quantifiable rating approach! Yay for science. :clap:

For total noobs (like me) I found RSD Academy's op-amps playlist to be pretty good - not on the youtubers list you linked.


Excellent effort by the way! ... will really help to cut down the noise from so many videos that are pretty weak :-+

Thank you

I will add this to the list of 25.  I will indicate that this is from a forum member.

There's an old video by Dan Bullard. This is the one video explanation that made the op amp really click for me. He connects the whole 'nothing goes in or out of the inverting/none inverting inputs' principal really well. I've probably watched that video half of his 231k views... maybe more... before I got the concept through my thick head.

I think Dave's video does it as well as any of the others I have seen.  I like the KCL approach - it brings a little formality to the process where handwaving doesn't.  Both approaches get the same answer.

The Dan Bullard video is quite good in that he keeps working that awkward feedback circuit.

Where we don't have videos worth much is for the topic of analog computing.  That is the original purpose for the op amp and those videos I watched this morning on solving differential equations just didn't do it (for me).  Among other things, analog computers rarely use differentiators because they tend to inject noise (high pass filter) whereas integrators tend to remove noise (low pass filter).

I remember talking about the equation for the Mass-Spring-Damper problem in grad school and we set up the equation easily (well, most did...).  But doing anything with it was maddening because the personal computer hadn't been invented.  We certainly didn't have Matlab.

With real op amp integrators (2) and an op amp inverter plus a 2 input op amp summer, we can see the system work on an oscilloscope.  In my case the integrators have a time constant of 1 so they work in real time.  The feedback capacitor is 1 ufd and the input resistor is 1 Mohm.  Oh, and there are a couple of potentiometers involved to set the constants and a scheme for setting the initial displacement (there is a force pulling down on the spring before it is released).

I have had more fun with differential equations in the last year than I ever had in college.  In undergrad, the HP 35 hadn't even been invented!

Just for giggles, I have attached a PDF of the Matlab version.  Matlab does a terrific job with this type of problem!

Op amps are fun!
