Need spice model for ADG419

Trying to simulate an ADG419 SPDT ( in a circuit I currently have but can't find any SPICE models. The closest I can find is ADG779 ( but this doesn't have Vss, or VL pins. Vss I assume is important for the signal (±10V signal), and VL is important for matching the simulated schematic to the actual schematic.

Could I get some recommendations for what I could use as a replacement or is there a model for ADG419 that might (hopefully) be archived somewhere?


  • Hi,

    There is no spice model available for the ADG419.

    One option is to use the ADG411 Spice model.  The ADG411 is 4 xSPST so you can use 2 channels and tie the outputs together to replicate an SPDT.  The ADG411 has the same core switch design as the ADG419 so it should give fair indication of performance.
