Hello,

 

I am tring to do noise simulation with the AD8045 spice model.

In ADISimPe the noise at 100KHz is 5.6nV/rtHz and not the 3nV/rtHz as told in the datasheet.

 

I also imported the spice model in TINA from TI and the noise at 100KHz is 6.3nV/rtHz

 

Also differend.

 

I use the latest revision of spice model(08/14/2013)

 

I also tried an AD4898-1 and AD8099 and these resuls matched with the datasheet.

 

Is there somthing wrong with the AD8045 Spice model???

 

Thanks for any reply,

Ronald
