Hello,

I have some questions about the spice model of AD5144.

(1) I downloaded the spice model from ADI WEB site. The file name is AD5144_10k.cir. But the first line of the description of the model is AD5140 SPICE MACROMODEL. Is this file correct spice model of AD5144?

(2) According to the description of the model, 9pin is for independent control. Could you please advise me the independent mode and pot mode?

(3) The model is for 10k ohms. Can I change the model to 100k ohms? If yes, how can I change it?

Best Regards,

Akira
