Are there some parameters I can change in the models for the ADG408/ADG409 parts to match how an ADG1408/ADG1409 would operate?
I have both spice models downloaded: AGD408/ADG409
I would like to simulate ADG1408/ADG1409
Thanks.

Hi Matthew,
I'll look into this. I'll get back to you soon.

Hi Matthew,
I've had a look at the difference between the ADG1408 and ADG408, these two devices does not have similar parametric values. On resistance for instance is from 4.7 ohms to 40 ohms respectively. Now, if you plan to change the ADG408 spice model to match the ADG1408 behavior I'm afraid you have to change the values of the component used in each parameter. Please be reminded that changing the component values inside the model would not necessarily mean a proportional outcome.

Hi Matthew,
Here are some points you might want to consider in editing the ADG408 spice model to make it close to the ADG1408 behavior.
* Main Series Switch combination
E_1_E 611 14 VALUE = {(10*V(73,500))/(V(421,500)+0.005)}
E_1_F 612 14 VALUE = {(10*V(73,500))/(V(500,422)+0.005)}
* Input capacitances
*
C_A0_1 4 14 8E-12
*...
* OFF Isolation
*
COI_1 4 8 1E-13
*...
ROI_1 4 1901 1.6E9
COI_1A 1901 8 10E-12
If you want to push through in editing the ADG408 spice file to make it close to the behavior of the ADG1408, I'm afraid you'd have to change every component values of the model. Also as mentioned from the previous reply, changing the values in the spice file does not mean proportional parameter outcome.

I see that the parametric values are indeed different. I would like to edit the ADG408 spice model in order to achieve something that is closer to what I would see with an ADG1408. I am having a hard time interpreting the spice file to know what to change to achieve my goal. There are headers for sections but - line by line are unknown characteristics. Can you help me with that part? I am having a hard time correlating from SPEC sheet to SPICE MODEL If what I am looking for is unfeasible then I will move on. Thank you for your help!
Example: (A few lines from the Spice file)
* Input capacitances
*
C_A0_1 4 14 8E-12
*...
* OFF Isolation
*
COI_1 4 8 1E-13
*...
ROI_1 4 1901 1.6E9
COI_1A 1901 8 10E-12
