    Does a document or resource exist that lists the differences between an AD7280 and an AD7280A ?

    I accidentally bought a large batch of AD7280, not realizing they were non-A at the time.  I suppose the non-A is older silicon.  The parts I ordered are NCNR so I guess I have to trash them unless I know what I'm signing up for if I use them on products which are already using the AD7280A
    

    

    Thanks for any info,
