ADA4084 SPICE Model

Hello,

 

I'm trying to use ADA4084 spice model inside of LTSpice. 

However, I'm getting errors "Singular matrix: check node u7:82 Iteration No.1", where u7 is one of the ADA4084 instances. 

 

I have read elsewhere online that LTSpice doesn't seem to place nicely with ADA noise models, and when I search for "82" in the ADA4084 spice model, it seems to be related to noise parameters.

 

Is there a solution for this, either modified SPICE model, or LTSpice setting that can help make the simulation run?

 

Thanks!
