They are not PLCC types, they just seems to be soldered types. What you think?? Shall I just use two 6 channel chips
How are you arranging the buttons, because the 160 only has AKS for the electrically adjacent inputs. (ie Pin sense two only has AKS for input one and three) As for the condensation, you could lower the sensitivity, plus on the wab site it says So I think that the condensation wouldn't mess with it, unless is was a drop of condensation rolling down the pads, but lowering the sensitivity should work with that.
