How is everyone doing? Quick question.
I downloaded TI's Instrumentation Amp model for a Part # INA121.
You can see it here: http://focus.ti.com/docs/prod/folders/print/ina121.html
I first make the library and symbols using model editor. When I go to a schematic and select the library, I see 4 different symbols. It looks like 3 of them are opamps and one is the device but the latter's pins don't match up.
My question is, why can't I get the one symbol that they have pictured in the datasheet? Why am I getting 4 and how do I use it to model the actual device? Do I just have to make the device from what is pictured in the datasheet?
I'm sorry if this is a silly question but I have never ran into this before.
Thank you.
