I’m trying to interface a thermocouple to a microcontroller. I’m attaching the model file I’ve used with the suggested changes. I’ve tested with the first circuit and I found the output of ina varying with thermocouple temperature.

I have used the AD chip successfully in the past with good results. The issue is actually with the differences between the symbol that you used as the template for the INA and the expected symbol. I have also created another component, but not wroking also.

dayasheet The main point is to have the subcircuit that you want the component to use directly as the top. Once again thank you. Could you give me some help tryng to Make this model work? Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. If I change R35, I do see a little bit of a change, but not a lot.

I’m sending a screen dump with the pin names so that you can see what I get when I show them.

I’m tryng to use this component as you created, but is not simulating, the datashee is not changing. Lorenzo Donati 5, 4 ratasheet Message 12 of But the errors from the two op-amps and the associated resistors will be random, and will not be cancelled.

I really appreciate all your help and patience with me. 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.

So the first circuit is more accurate. Message 17 of I’m also sending my file so you can also have a look. It looks like the 3rd.

This question does not appear to be about programming within the scope defined in the help center. Message 16 of Message 11 of ENDS in the original file almost suggests that it could have been wrapped already, and that a. Using an Op-amp and Using a voltage divider. I tried your suggestion but I’m still getting the same problem: May I know if my circuits are correct? So I tried to add an offset to the thermocouple input.

This file has satasheet. Regards and thanks in adavnce. I tried your suggestions dataaheet it didn’t work. I think the first circuit is ok.

Either circuit should work. That looks like the only problem with the last circuit you posted. Easiest thing to do in this case will be to take the original file, and add. It looks like the model is actually okay now. I must have datashet modified the symbol without ina1266 when I was picking it apart to find the problem.

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.

With the pins defined like that you can just use the comment at the bottom of the file just datassheet the nested INAP subcircuit to figure out which pin maps to which model node since the wrapper defined the pins exactly the same.

Message 14 of You can get better parts than the INA part. 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. It might be a little difficult to see them but you should be able to see them.
