I really appreciate all your help and patience with me.

If this question can be reworded to fit the rules in the help centerplease edit the question. I’m also sending my file so you can also have a look.

That looks like the only problem with the last circuit you posted. Now everything is working well and I can carry on with my simulations.

Micropower Instrumentation Amplifier Single And Dual Versions

If you swap the wires on pins 1 and 5, you’ll probably get the simulation results you expect, but then of course ina16 wiring is wrong. Using the file that you just attached, the wiring looks okay, the pins all look correct.

I’ve tested with the first circuit and I found the output of ina varying with thermocouple temperature. I’m trying to interface a thermocouple to a microcontroller. So the first circuit is more accurate. I’m attaching the model file I’ve used with the suggested changes. Message 18 of I have also created another component, but not wroking also.

As the thermocouple produces a very low voltage, I use an INAP instrumentation amplifier to amplify the datashheet. Using an Op-amp and Using a voltage divider.


Also, pay very close attention to the voltage levels with regard to the rails. 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 looks like the model is actually okay now. ENDS in the original file almost suggests that it could have been wrapped already, and that a. You can get better parts than the INA part. And the 1K’s could probably be 10K, if you want to save some current.

Message 16 of 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 This will make the first subcircuit in the text a subcircuit named INAP, ending with the “extra”. I’m sending a screen dump with the pin names so that you can see what I get when I show them. It might be a little difficult to see them but you should be able to see them. Regards and thanks in adavnce. Message 12 of Hello all Mulstim users.

Once again thank you. Most Active Software Boards: Message 19 of This file has three. Message 15 of I have used the AD chip successfully in the past with good results.

I tried your suggestion but I’m still getting the same problem: Stack Overflow works best with JavaScript enabled.

I tried your suggestions and it didn’t work. Beware that the output voltage will not go rail to rail also. I’m tryng to use this component as you created, but is not simulating, the gain is not changing.


Message 20 of With the pins defined like that you can just use the comment at the bottom of the file just above the nested INAP subcircuit to figure out which pin maps to which model node since the wrapper defined the pins exactly the same. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. I’m starting to think that there’s an instalation problem with my software and maybe that’s what’s causing the problem now.

I guess that because I wanted to isolate the problem I designed the dahasheet 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.

I also tried changing the symbol to model pins but that also didn’t work, it just made it worst. I believe it has better offset specs, which is the most important spec in a thermocouple xatasheet.

Message 13 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. This question does not appear to be about programming within the scope defined in the help center.

I tried making all possible connections between pins 1, 8 and 5 and that still didn’t help. Could you give me some help tryng to Make this model work? 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.
