AD8332 Amplifier, Is noise modeled?

Hello,

 

I am getting poor results trying to model noise when using the AD8332 in Orcad PSpice.  When looking at input referred noise with a shorted AC coupled input, I am seeing around a 200nV/rtHz noise floor (specs claim as low as .74nV/rtHz).  Can Analog confirm or deny that the AD8332 model posted on the web can be used to look at noise for this amplifier?  It would seem like given the applications for this amp that noise would be modeled.   If it can I will post my schematics and plots to see if anyone can point out what I am doing wrong.  Thanks for any info you may have.

 

Kevin
