Please correct this if I am wrong, but I believe you are referring to the Generic ADC that is in the database. This thing does not work or at least I could not get it to work. I made one from a previous version of Multisim and made a component for Version 10 that does seem to work. Goto the website in my signature, register (it is totally free) and look in the downloads area.
Please let me know it this is what you needed.
