  There are currently 8 of us in a group studying op amps for an exam literally tomorrow. You have saved 8 lives

  I got a B.S. degree in electric engineering 30 years ago.  After getting brain cancer,  lost so much memory and your videos sometimes bring back some of my memories.   Thank you.

  "This is a non-operational amplifier" got me lol xD

  As far as I know, they are called operational amplifiers because they were used to perform mathematical operations on analog signals, like addition, subtraction, differentiation, and integration. It's very interesting how you can use it in integration mode to produce a triangular signal from a sqaure signal.

  As a former teacher I can say this is an amazing video! Not only is everything correct on the point but it also gos deep but still manage to be funny and engaging. 🤯🤯🤯

  I have been following the electroboom 101 series for over 6 years, ranging from the history of electric charge down to OP-AMP<br><br>Great tutor,Mehdi.

  This is over 40 years to late for me, as I have been designing and building circuits using OpAmps since the early 1980s. Another commenter has already mentioned the IC Op-Amp Cookbook, by Walter Jung as a great book if you want to learn more, I concur. As for the origin of the name, the following is a quote from the book.<br><br>The original concept of the operational amplifier came from the field of analogue computers, where operational techniques were used as early as the 1940s. The name operational amplifier derives from the concept of an extremely high gain, differential input dc amplifier, the operating characteristics of which were determined by the feedback elements used with it. By changing the types and arrangement of the feedback elements, different analogue operations could be implemented; to a large degree, the overall circuit characteristics were determined only by these feedback elements. Thus, the same amplifier was able to perform a variety of operations, and the gradual development of operational amplifiers grew into the beginning of a new era in circuit design concepts.<br><br>A suggestion for a live build along is a full wave rectifier. Not something probably associated with OpAmps, but on theme with the channel.

  Opamps are so useful for intended and unintended circuits

  Im a electronics tech with 30 years + experience i replaced so many of these little suckers in tv sets back in the day that all died from the same cause. direct tv. For several years straight direct tv would lower the show volume just before a commercial would come on and peoples normal reaction was to increase the volume to hear the show. Then when the commercial would come on they would increase it&apos;s volume. This sudden surge would pop these opamps real fast. Direct tv was not doing it to fry tv sets instead they were doing it so people would not miss the commercial audio very un cool thing to do. they wanted that money from advertisers so bad they basically said screw the quality of the show people wanted to watch. I made good money during this time period off the repairs and direct tv lost a ton of customers as well LOL <br><br>Eventually the cause was posted to a great many forums costing direct tv more customers and making tech more money and direct tv ended their practice. Another fun one during this time i got a whack load of fairly high end tvs off the curb that had blown opamps for the sound amplification lol &nbsp; I also found out that in some cases the difference between a stereo tv and a mono one was well a single missing opamp and the space for it was right on the board as was the speaker output LOL

  More like PopAmps when Mehdi uses them.
