Hi All. OK, I give ... what is the difference between these two chips ??

I've read both spec sheets, and they seem to be identical. Are they ?? Can
they be used interchangeably ?? Both appear to be in current production.

Any clues would be great !!

They are pretty much the same thing. The 612 has looser specs.
I suspect for anything where it can be used, it wouldn't matter too much
which one you choose.

Keep in mind that it's not necessarily the best choice for a mixer
with strong signal handling capabilities, it was afterall originally
intended as a second mixer after filtering, but that shouldn't come
into play between the 602 and the 612.
