Once again thank you. As the thermocouple produces a very low voltage, I use an INAP instrumentation amplifier to amplify the voltage. Using the file that you just attached, the wiring dagasheet okay, the pins all look correct.

But, is the second one correct? I think the first circuit is ok. Either circuit should work. You don’t need the 10K resistor on the input, as the 1K’s will do the same function. Multisim components require a single “.
I’ve done that in two ways: You can get better ina1226 than the INA part. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. I would perhaps use both in conjunction with one another.
datasheeg Message 13 of I’m tryng to use this component as you created, but is not simulating, the gain is not changing. It might be a little difficult to see them but you should be able to see them. I have used the AD chip successfully in the past with good results.
By the way, if it helps at all, I’m comparing by doing a parameter sweep over the ian126 value using the values mentioned above. So the first circuit is more accurate. Message 12 of Easiest thing to do in this case will be to take the original file, and add.
Could you give me some help tryng datasheeet Make this model work? If this question can be reworded to fit the rules in the help centerplease edit the question. This file has three. Message 19 of I’ve done that in two ways:. Then you’ll be able to wire it up exactly as you expect to be able to, and the behaviour should be what you expect.
You need to either adjust the three subcircuits so that the correct one comes first and preferably nest the other two inside it – that will be important if you want to use more than one of the component in a circuitor just wrap all three.

The issue is actually with the differences between the symbol that you used as the template for the INA and the expected symbol. I tried dtasheet suggestions and it didn’t work. 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.
So tomorrow I’ll get it reinstalled and try your suggestions again and I’ll get back to you. 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. Hello all Mulstim users.

Using an Op-amp and Using a voltage divider. Message 20 of Now everything is working well and I can carry on with my simulations. The divider one is better from an error standpoint because the offset voltage from the divider is common mode input to the amplifier, so it will be cancelled. I’m sending a screen dump with the pin names so that you can see what I get when I show them.
It datasheef like the model is actually okay now. With the pins defined like that you can just use the comment at the bottom of the file just dataxheet the nested INAP subcircuit to figure out which pin maps to which model node since ina1126 wrapper defined the pins exactly the same. Message 11 of Message 18 of If you show the pin names on the schematic in the Display tab of the component properties you’ll be able to see the differences.
There might be a way to get this model to behave as you want it to, actually. ija126
I think I’m going to ask the IT support here at my university to reinstall the software. If I change R35, I do see a little bit of a change, but not a lot. Also, pay very close attention to the voltage levels with regard to the rails. I’m trying to interface a thermocouple to a microcontroller.
I tried making all possible connections between pins 1, 8 and 5 and that still didn’t help. Since it will be the first thing in the listing, Multisim will see an 8 pin subcircuit, which just uses the 8-pin INAP defined below which in turn uses the other two op-amp subcircuits.
It looks like the 3rd.
