Re: ADA4895 SPICE model accuracy

Hi Dave,

 

The header in the model (file name "ADA4895.cir") says:

* Developed by: C. El Khoury

* Revision History: 1.0 (9/2012) – CE – initial release

* Copyright 2012 by Analog Devices, Inc.

 

I downloaded it from the ADA4895 product page yesterday.

 

I simulated the model in LTspice, small signal analysis, +/-5 V supply, open loop, and added a small input voltage manually to get an operating point with the output close to zero.  I don't think this is related to any specific simulator though, if you look at the model netlist you can see that the sections labeled third/fourth/fifth pole and first/second/third zero are all placed at 1 THz.

 

Hans
