ericgibbs, please help a poor soul. I have tried a sym AD620, but I get errors like "unknown subcircuit called" in LTSpice IV.

hi,
All the AD620 information is here, **broken link removed**

also attached a zip with *.cir and *.asy

If you have a problem , post your asc file.

BTW: you do not include AD620.asy but AD620.cir or AD620.mod

hi,
Try this asc file.

NOTE: the text information required on the circuit.

ericgibbs, to say thank you is necessary when somebody helps you and it's mandatory when the help is given at the right moment.

The ".cir" file in my case wasn't in the same directory withe the ".asc" file. I think this was the biggest problem.

In order to help somebody else in need I have put here an archive with the files you gave me, with a little extra: a Wheatstone bridge

All the best!
