AD4898 SPICE model shows incorrect gain/phase vs. frequncy plots

Hello,

I tried to simulate the open-loop gain & frequency of the AD4898 to verify it follows the datasheet and to design an active low-pass filter.

I used the new SPICE model posted here at the forums, version REV.4.0 Jul 2016-ZF.

The datasheets has a plot of open-loop gain with GBW at about 100MHz, while the spice simulation shows ~52MHz.

 

Does the spice model is accurate enough for designing circuits,

or my whole design will get wrong output results because of a faulty model?

 

Attached a screenshot of the simulation output

 

Thanks
