Production
The AD817 is a low cost, low power, single/dual supply, high speed op amp which is ideally suited for a broad spectrum of signal conditioning and data...
Datasheet
AD817 on Analog.com
I Have AD817.cir from analog site, but I have no idea how to use it on LTspice?
there is whats inside it:

Hi,
Download the AD817.cir file from Analog site.
Open it using your LTspice program.
Point on the line where the ".subckt" line and right click on it to create symbol.
The box symbol created is located on the "Auto-generated" library in LTspice.
Hope this helps.

Thanks, But how to change and make our own shape for it's symbol? Is there any reference?
And do you have any idea, why the model not works correctly?
this is RtoR but it clamps!!!
Hi,
Unfortunately, ADA4851spice model have some problem.
What application are you working on? Maybe we could give you some advice based on that on what part to select.
What particular parameter are you concerned?
Right now, your option is to just choose other part spice model closed to ADA4851 depending upon your application.
any idea?
I have same issuer with ADA8282 can you please verify if that is correct?
