Does anyone have, or know where to find, a model for one of these dual supply, SPDT analog switches?
My LTSpice has a voltage controlled SPST switch. Two of these could easily make a SPDT switch.
Hmm. I don't see one in the Maxim info page (the "Models" option is greyed out):
Is Maxim the only manufacturer?
Tried Maxim and Intersil, neither has a model available. I am using Orcard 16.2, and it only has user controlled SPST or SPDT switches. I need to be able to switch inputs dynamically at 10kHz.
I would use the simplified schematic from the part datasheets, and add components to model the capacitances and other values in the datasheets. That will give you a reasonable starting point, especially for 10kHz.
A good book for tuning up models is "Semiconductor Device Modeling with SPICE", edited by Antognetti and Massobrio. Your school library may have a copy.
