Hackaday Intro to Instrumentation Amplifiers

[@w2aew]

Nice video Bill. FYI - you could use hi-res sampling in the MDO to increase vertical resolution and low pass filter (noise filter) the noisy output signal.

[@AdamOutler]

Awesome tutorial, HACKADAY ! It's been a long time since I've had an opportunity to look at op-amps. Please keep these coming. This is useful for Raspi and arduino projects when setting up monitoring for any sort of project.

[@JacobKinsley]

I had no idea that instrumentation amps existed so I spent ages googling weird combinations of words until I found this, the answer to all my problems

[@XTL_prime]

This was excellent. Probably better than any other lecture or talk on the subject. I for one would love to see a pragmatic "quieting down" video too.

[@Nikkuuu69]

Very interesting video! I can't wait for part 2.

[@PirateFunk]

You make an otherwise dry topic sound extremely interesting!

[@agstechnicalsupport]

A very good introduction into instrumentation amplifiers. Thank you !

[@dylankane5919]

Very informative video. I love the way you convey ideas!

[@SkyhawkSteve]

dang... I thought I was the only person who has kept their PMI databook for all of these decades! Nice intro in into I.A.'s. Thanks for the review.

[@sysmatt]

Good info, looking forward to pt2

[@7head7metal7]

Awesome, thank You Bill! :) I'm very curious about the layout part, hope it will come soon :) Greetings from Germany :)

[@freeelectron8261]

Nice IA video Bil. Thanks!

[@bigk6341]

Hey Bil, I'm trying hard to understand in amp with single supply, could you please explain waht happens if this in amp would be connected to single supply ? Thank you very much

[@ekavenel]

Bil, loved this video, and those on PSoc. Can PSoc provide a good Instrumentation Ampflier to be part of a application?

[@jingyusu2057]

It would be great if can you do an episode to quiet the circuit down?

[@stephanc7192]

Bery nice video! Thank you

[@fstopspictures8834]

can we use this after a preamp to set levels for the adc ?

[@bamokinamoandadestin7888]

Nice class!

[@coffeecuppepsi]

hi, hoping someone here can help me!I'm trying to use an Instrumentation Amplifier on a 2MHz balanced signal. the parasitic capacitance of my IA is 10pF or just under 8k ohm at 2MHz... the equivalent series input impedance circuit is 0.06 -7957i according to what I calculated...I need the highest possible input impedance, so to cancel out the parasitic C may I put an inductor in parallel with it? I ask cause I haven't found schematics where that's done and google search hasn't led me to relevant articles, yet..cheers :)

[@johnnyprimavera2]

Micromillimeters are 1e-3 x 1e-6 = nanometers?

[@ottoomen5076]

Thanks homie.

[@macbrinechangwe830]

hackaday what abaut LPC logical programmeable computers?

[@harviecz]

Thanks! I now understand the basic concept of the inamp, but i am still not unable to understand role of all resistors in the circuit. Can you please make in depth video explaining function of all 7 resistors that are present in inamp circuit? (and the 5 resistors in simplified circuit). It's still unclear to me how the gain is set in different stages.

[@harviecz]

Eg. i don't get why i can't just use plain opamp buffer (opamp with output tied to negative input) to buffer both inamp inputs. You don't need any resistors to make voltage buffer using opamp.

[@coolwinder]

What's the music?

[@Neslekkim]

That box of sensors, is that a kit sold somewhere?, if so where?

[@cymeriandesigns]

I saw something that looks like that on aliexpress.com. Search for arduino sensor kit on the site.

[@BlOoDyRhUm26]

Bien le bonjour ! Vidéo intéressante, mais étant français, certaine partie ne sont pas claire pour moi (difficulté a comprendre l'oral anglais). Serait-il possible de mettre des sous-titres ? Merci. Cordialement. Ps: serait il possible d'avoir le nom de la musique de fin ? =) ------------------------------------------------------------------------------------------------ Hello World! Interesting video, but being French, some part is not clear to me (difficulty understanding English spoken). Would it be possible to put subtitles? Thank you. Best Regards. Ps: is it possible to have the name of the end music? =)

[@anitabora9935]

How we design this circuit on pcb

[@shubhayudas6273]

I'm extremely late here, but I think you made a mistake at 04:55. The voltage the inverting input is not 0V. It is equal to the voltage across the Rg resistor, essentially the voltage at the non-inverting input

[@brandonlewis2599]

Nice video, but can you please turn the volume down on your music? Or better yet, just get rid of the music at the end. I turn the volume up so I can hear you speak, and then I get blasted with techno at the end at high volume.

[@JohnFHendry]

Good descriptions... but a brain dump would be so much faster at my rate;-)

[@zikomo8913]

Hmm......a High Speed Digital Design book.
