There are eight pins of AD8310,but only seven node assignments,com pin is not included,can you explain why?
To follow-up on what Anna posted: the ground used is node '0' (zero) in the model, which is absolute ground in SPICE. I could have brought this out, but it is not needed and SPICE will run it as is. You can look at the sub-circuit and see this; it is indeed grounded internally.
The Common pin (pin2) of AD8310 is just the ground pin so the SPICE model designer opt not to include this in the SPICE model. But be sure that in using this SPICE model or other SPICE models, you should have a common point for all your ground connections.
