Noise of AD821 device

Dear all,

 

I am designing a filter using AD8021 device.

 

This device is characterized for +-5V and +-12V power supply.

 

The figure for the voltage noise spectral density is related at +-5V Power Supply (maybe).

 

Anyone knows how is the noise figure,  using +-12V  for Power Supply?

 

I've tried to use Spice simulator but the simulator presents the same results for both +-5V and +-12V, and I think this could be a limitation of the model of the device. Also, for example, if I use different temperatures in the simulation the minimum for obtain results is -29 Celsius degrees.

 

Thank you for any useful advice!

 

Regards Davide
