I really enjoy your channel. I just discovered it yesterday looking at your OTA video. It caught my eye and it was very interesting. I learned something new about a little known component. This video has been equally informative so I am now convinced. You have a genius level skill set for teaching complex subjects pertaining to EE and Physics. The relaxed delivery and thorough breakdown of the content into easy to digest analogues makes it possible to grasp it with a fuller understanding. By all means, keep them coming and thanks (I'm a 3rd your EE student for reference purposes).
Excellent concept and demonstration! However, I measured my Arduino Nano, the resistance at Aref pin is around 2.978M ohms, not 32k as you said in the video.
It takes about 100 microseconds to do an analog read on an Arduino, so that's only about 10kHz at absolute maximum, and that's assuming you spend no time at all actually doing anything with the number you read. So probably any op-amp and capacitor would be able to handle it, but you could tweak it if necessary.

New video! the day couldn't be better : D
well described.. glad to find you sir.... thankssssss
great explanation as usual, thank you.
Nice video love from India
very helpful, thanks.
Hii plz make a video on over voltage protection circuit for Arduino ADC
nice!!

dumbass
If in doubt, use an op amp :)
Hey man. Why did you stop posting???????
i missed the capacity mention, is it in NF region? will it mess up with the op amp at higher freq?
