Peter Green is right. We need 6 ADCs.

but you should be able to do keyboard matrix scanning to cover 16 buttons, 4 input 4 output... unless you really really want all possible button combinations, hmmm...
are there any keys which may not be pressed together, so you can do matrix-scanning on those, at least?
Matrix-scanning is not a good idea. We want all possible button combinations.
Thanks.
