Is a marking specification or datasheet with part markings available for the DAD2000 (2506593-4)? I would prefer to have it spelled out line-by-line what specific characters are date & lot code as well as any die revision codes and options (voltages, etc). This is usually at least in the part markings database at http://focus.ti.com/general/docs/partmarking/partmarkinghome.jsp or listed in the orderable parts in a datasheet. Thanks.
