106. Instrumentation Amplifiers
A video that's far too long :)
This video goes over the basics of Instrumentation Amplifiers: theory of operation, useful features, how gain is calculated, and tests of gain, CMRR, and CMR.

Found a little error in the way I explained the derivation of the formula - the result of the equation is correct though. It's near the end of the explanation - I'll leave it to the eagle-eyed to discover. Again, the answer is right, my explanation was off.

Thanks again for the super outstanding effort that leaves anyone able to understand and learn. Very great as always.
Fantastic tutorial, not too long !......cheers.
That resistor trimming tip is a neat trick. Great video!

I am not sure I caught this point. At what time does it occur in the video. Thanks for this help.
Best Op Amp/In Amp tutorials on youtube. Hands down. Bring the Viking Back! LOL

Wow, thanks!
EXCELLENT PRESENTATION.
Thank you for the excellent video! I am a self-taught EE hobbyist and only have hobbyist needs. I was considering building an In Amp from scratch for learning purposes, but due to the precision parts/resistors needed, I am considering an all-in-one package. With the gain of the AD2221 (correct #?) not reaching its expected goal and its function left uncertain, I am wondering two things... 1) Should I feel confident enough to use the 2221? 2) what other chips should I consider, having a price point of $20USD, or less?

I see that the correct part number is AD8221.
Very nice presentation, thank you.

Glad you liked it!
Sorry Sir, there are more than one error. In 17:50 (2R1+1)/RG is wrong. Later you use the right term (2R1/RG + 1) . VOUT = (R4/R3)*(VA-VD) is wrong. It is VOUT = (R4/R3)*(VD-VA). Where is R5 and R6?
Thank you
Super
wow very nice
