There is a small error in ADA4897 spice model, where node 106 (PD) should be DISABLE bar, i.e., when 106 pulled to -VS + 0.7 V, AD4897 will be put into disable mode.
I believe the ADA4897 SPICE model is working fine. The part will be disabled if PD (106) < +Vs - 2V.
I mean that this pin should be named as DISABLE#, rather that PD. When we build a symbol using A, we usually mean that A is a HIGH valid signal, for example PD means this chip is Power Down when PD is HIGH. For A#, we mean that A is a LOW valid signal, DISABLE# means that this chip is disabled when this pin is LOW.
We will see on what we can do on this suggestion. Thanks.
The name is immaterial. If you put it on a schematic, and connect a wire, you can call the wire
"THISISHIGHTOENABLE" or "xxx" The "PD" is what software engineers call a formal parameter;
it is a placeholder. You could change it to "EN" which stand for Enable if it will make you happy.
