I can't find what the A suffix is for... it'll be some kind of package designation, probably something like extended temperature functioning range so I wouldn't worry about it not having it.

Be careful they're not fakes though, i'd never seen a fake SAD1024 before but when looking for this information I found this shot

Which looks very suspicious to me.

Which means... it could be any old chip, the photo is from one of those Asian wholesale sites so I would assume, unless they found hundreds of SAD's, that it's a fake and not just a reprint of an original (which I never quite understood the reason for doing).

That sure is a nice sanded PT2399. They could have at least reprinted "RETICON" in the correct font! Looks like they're getting downright lazy with the fakes.
