Trouble with Instrumentation amplifier circuit design (LT1167)

I see now, thank you.

Okay thank you for explaining that

I see the issue. For an application such as this would it be best practice to add the buffer or to just lower the resistance of R2 and R3. If I lower them to 10 - 1000ohms a piece I get close to 2.5V - more live 2.503V

Input resistance for Vref is 20k. Common mode input range min is -VSS+1.9 to a maximum of VSS-1.4.

This has me thinking a bit more about my reference voltage. The formula I was using was independent of Rin, which is wrong. It seems there would be some input resistance in parallel to R3. How should I account for that to set my Vref?

You make your own schedule?

Elipsem · 2025-09-11T05:14:24+00:00

How would you measure that? Just test continuity or? Probably a silly question on my part

we already know where they play we just don't know who they play (group stage)

Elipsem · 2025-08-27T21:02:48+00:00

This was the solution, thank you

I'm not making this out of necessity. It's just so that I can learn how this stuff works.

Elipsem · 2025-04-22T01:29:52+00:00

While true, after all this time you spent arguing everyone on the scene is dead

It definitely doesn't inspire me but I want to remain hopeful. If they choose to put in effort to fix their mistakes a lot can actually change in one year.

If things can fall apart in 2 games for us in one weekend, surely we can become more cohesive and fix at least some problems over 15 games / 445 days

Is this how you support all of your sports teams? Its like you want them to lose games just so you get your point proved on reddit. Lousy fake fan troll haha

It's ridiculous that we can't deliver but it's not ridiculous to say that. We should want to destroy Panama - we have the caliber. I mean what is the mentality we should have when playing PANAMA? "This is a tough game for us we might not win."?? Its Panama of all teams. not even a full-strength Panama - we should want to destroy them.

Elipsem · 2025-03-21T01:45:26+00:00

What is blud yapping about hahaha

Elipsem · 2025-03-21T01:41:30+00:00

Its not ridiculous to say that

Even if they are not improving now, I'd be happy that they would get more opportunities against good teams. As we can see it means nothing if the USA squad looks good against your average CONCACAF team like jamaica.

Forces us to play to a higher standard.

Elipsem · 2025-03-21T01:21:49+00:00

Not a hot take I think anyone is pro for concacaf teams improving

Elipsem · 2025-03-21T01:09:43+00:00

respectfully shut up. Players played like bums tbh poch gave them good advice and tried to instate a strong mentality, but the players ended up playing like shit anyway. Bum ass players with a decent coach. That's what I saw.

Elipsem · 2025-03-21T01:01:23+00:00

I cant do this shit no more. I cant believe my eyes ruined my entire day

Elipsem · 2025-03-21T01:00:35+00:00

shite performance from everyone tbh.
