Noise in ADA4817 SPICE Model

Hi

 

I noticed a mismatch in voltage noise performance between the datasheet (4nV/rtHz) and the SPICE model (~2.5nV/rtHz) of the ADA4817. I use Microcap 9.X and connected the Amp as a simple voltage follower. Can someone confirm this behaviour on another simulator? Maybe a statement of an ADI-Engineer would be helpful ;-)

 

Best Regards,

Fabian
