ADS7950: Questa simulation model

Hello,

There is an IBIS model available in the device web page

There is no spice model, we unfortunately do not have one available.

But we do provide video directions as to how to build and simulation the analog input of an ADC, you can follow this in any spice model. The video uses TINA, a spice based simulator.
