I am keenly interested in using the AD8397 op-amps in a motion-control application for resolver-drive. I am trying to model the circuit with a range of loads to evaluate stability, etc., but am having difficulties with the SPICE model for the AD8397. In particular, node 9 of the model does not appear to make any connection beyond the Ecmr line:

Ecmr 10 9 603 0 1.000E+00

So the question is - is the correct behavior to ignore this error / comment out that line, or should there be another connection to node 9 somewhere else? I expect one of the ADI op-amp wizards will know right away, thus this post rather than drawing the circuit and trying to work out what should really be going on here.

Hi Stephen,

Thanks for using the AD8397. Could you elaborate on the errors that you're seeing and at what configurations you're seeing them on? I'll be feeding this issue to the engineer who worked on this part and more information from you could help us figure out the error.

Thanks!

Kris
