I designed a butter-worth 4th order filter with Fc = 3.5KHz,
I wish to use the part OP496GS.
For verification of the design I acquired the psice model of the part OP196.
I am using Multisim 10.1 for simulation of my circuit.
When I am doing the AC analysis I am getting error. (Error is "Iteration limit reached").
Whereas my design meets all the criteria when I replaced the model with ADA4857.
I am getting the same error if I am using the OP496 model from Multisim's library.
Please let me know is it the problem with Model of OP196 or it is the problem with device?
I am attaching the screen shot of my circuit for your refernce.
Expecting your comments as I am about to start the layout using this part.
