I am trying to simulate a simple circuit using the opamp LMC662 from Texas Instruments. I imported the file as provided in the product website: www.ti.com/product/LMC662/toolssoftware However whenever I run any simulation i get the error: G4: unknown circuit node: "1" requested in behavioral source. I have no idea what this means and how to solve it. Only thing that I found is that in the model file there are the lines:

G4 98 16 POLY(2) 1 49 2 49 0 3.54E-8 3.54E-8

G4 98 16 POLY(2) 1 49 2 49 0 3.54E-8 3.54E-8

which refer to node 1, which is defined as the non-inverting input of the opamp:

.SUBCKT LMC662/NS 1 2 99 50 28

Im attaching a screenshot of the schematic.simulation stops with this error

Any help is greatly appreciated!

PS: The ltspice model is here (it's in the zip file).

    \$\begingroup\$ can you share the LTSpice file too? \$\endgroup\$ – User323693 Feb 21 '17 at 10:49

  • \$\begingroup\$ hmm that is strange. I am able to download the zip file without being logged in to Onedrive. Can you check again? Initially I had uploaded just the .asc file but afterwards I uploaded a zip containing the whole project folder. \$\endgroup\$ – capitan Feb 22 '17 at 10:52

I managed to solve the problem by using a different library from National Instruments which contained the LMC662/NS. It can be found here. I still have no idea what was wrong with the original one.
