AD8479 Noise Density SImulation

Hello,

i'm trying to reproduce the results from the datasheet for the AD8479 spice model using LTSpice.  I've put together a very simple test bench to examine the noise performance and looking to integrate the noise for RMS noise to match the datasheet which shows ~30uVrms from 0.01Hz to 10Hz.  i put together the below and the results show a spectral noise density of ~6.5uVrms.  Am i wrong with how i am using LTSpice for this sim?
