AD8390 or AD8390A For Differntial Audio Output Stage

The AD8390 seems an excellent candidate for use in a differential drive stage for an audio-frequency drive to a resolver in a motion-control situation.  Is there any particular concern or reason why this would not work, or why this is a poor choice?  We need roughly the full drive capacity of the chip in some applications, though the actual drive requirements will vary a lot from application to application.  Some will be highly inductive, some nearly purely resistive, and some may be slightly capacitive.

 

These parts also look like they would make killer headphone amplifier final-drive stages, anyone try this yet?

 

Is there a SPICE model available for the AD8390 or AD8390A?
