Hi all,
today I downloaded the spice model for the OPA547 from TI's website, the zip file is called sbom087. I'm not sure if I saved it wrong or something, because when I use the part in schematics and run a simulation, I get a message telling me that the part is undefined.

Are you using TI's symbol? There has to be a .INCLUDE or .MODEL statement to link to the sub-circuit. The instance must also have a parameter that points to the sub-circuit.

You did unzip the file, right?

yes, I am using TI's symbol, it has all the same pin labels as the datasheet.
Where should I extract the files to? I tried saving everything to the pspice library, it is still saying that the subcircuit is undefined. By unzip I guess you mean extracting it to the pspice library like I did.

hi,
Will you zip up and post all these files and your *.asc, so that we can see where the problem may be.:)
