It might be a little difficult to see them but you should be able to see them. So the first circuit is more accurate. Message 19 of You can get better parts than the INA part. I would suggest that the easiest way to get the pin setup as expected is to create the component using the INA in the master database as the starting symbol since it has the pin names and numbers matching the INA data sheet, just with a different model. I think I’m going to ask the IT support here at my university to reinstall the software.

I would perhaps use both in conjunction with one another. The gain that i Should have with no resistor applyng 2V at the imput terminal should be 10V and so on, Gain 5, if I apply 1V, should be 5 and so on Message 15 of There might be a way to get this model to behave as you want it to, actually.


I must have accidentally modified the symbol without noticing when I was picking it apart to find the problem. The issue is actually datashest the differences between the symbol that you used as the template for the INA and the expected symbol.

So tomorrow I’ll get it reinstalled and try your suggestions again and I’ll get back to you. I really appreciate all your help and patience with me.

By datashete our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. Basically do the same thing you did when creating the component the first time, but just with a different starting symbol, and of course using the fixed up model that you have. I’m also sending my file so you can also have a look. I’ve done that in two ways: Multisim components require a single “. Message 16 of I tried making all possible connections between pins 1, 8 and 5 and that still didn’t help.

Easiest thing to do in this case will be to take the original file, and add.

I believe it has better offset specs, which is the most important spec in a thermocouple amplifier. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. By datasheeet way, if it helps at all, I’m comparing by doing a parameter sweep over the resistor value using the values mentioned above.


Message 11 of I guess that because I wanted to isolate the problem I designed the most simple circuit as possible and forgot to pay attention to a few details like having the reference pin connected to a midway voltage between the power rails. Either circuit should work.

I think the first circuit is ok. If you swap the wires on pins 1 and 5, you’ll probably get the simulation results you expect, but then of course the wiring is wrong.

Most Active Software Boards: Message 17 of And the 1K’s could probably be 10K, if you want to save some current. The divider one is better from an error standpoint because the offset voltage from the divider is common mode dztasheet to the amplifier, so it will be cancelled.

This question does not appear to be about programming within the scope defined in the help center.

It looks like the model is actually okay now. You don’t need the 10K resistor on the input, as the 1K’s will do the same function.
