    Today we're going to learn 2 golden rules to help us analyse any operational amplifier (op amp) circuit. We're going to apply those rules to crate a really simple to build DIY active low pass filter!

    Nice work explaining these concepts. As an EE, i'm able to track regardless, but you used terms that were both correct and simple (which is a nice skill). You also cut the video nicely and kept it short and on-point. Well done. sub'd.

    CD4069 is a Logic IC and not an OP-Amp nor an Amplifier. The IC has nothing to do with an OP-Amp or an Amplifier !

    Heeeeeyyyyy op amps just clicked

    My van is on your t-shirt!!! Well, maybe not mine personally, but I drove a 62 for a couple years back in the 90's. I love your channel.

    Thanks for posting. If + input of opamp starts at 1 at peak of osc and - input starts at 0, then diff is 1 so it outputs 1 and then the diff is 0, so…..how does that function if diff is 0 at that point? Basically it seems as though it would outputting a binary toggle as voltage is + on + input.

    Another great video, thanks! However, I was confused about one thing - I’ve played around with tl072s and similar as op amps, but when I looked at the data sheet for the CD4069UB, it says it’s a hex inverter, and I don’t quite understand how this works. Would it only work with square wave type “logic” signals that only have a high and low state? I don’t understand how it’s able to provide voltages besides supply and ground. Still a real beginner and maybe I’ve forgotten something fundamental from an earlier video?

    Incredible explanation mate! EE student here and your simple explanations really have helped me get my intuitions together regarding op-amps. Subscribed!

    Great video! I started my first big analog synth project recently and this was helpful background. I don't have much EE background so very helpful

    What is the white guitar behind you at the end?

    The CD4069 is a six-fold inverter, tha CD40106 is a six-fold Schmitt-trigger inverter. I don't understand the relation of these devices to an op amp. Or these CMOS inverters also used as "low cost" op amps?

    I've had trouble understanding how op amps work but you've helped clarify several points. Thank you for the great explanation

    Was having trouble with opamps all week, this helped!

  • @scrummyvision

    holy shit what an action-packed and well done video. this connected a lot of ancient college memories to what I'm working on now. thanks!

    Very helpful video for understanding why the resistors are important to the feedback. Thanks

    Well done mate - reaaaly nice, logical explanation!! - Kudos from Oz

  • @euglossine4ever

    this is exactly the explanation i was looking for , lmao even the chip is the same as i am messing with, tysm
