I am using the excel based design tool. I always get this error:
ADIsimPE simulation model exists for this product?
I am sorry that you are getting this error. Just to make sure, I just downloaded the most recent copy of the tool and it works fine on my computer. I attached the most recent version from the web. Did it work when you downloaded, or is your particular set of inputs that made it crash? What version of Excel are you using? Are you in a country that uses commas instead of periods as the decimal place?
We do have an ADIsimPE simulation of this IC. Just use the large button at the top of the tool to output directly to ADIsimPE... once we get you a file that works.
