Hi
I am designing a capacitive touch switch board using CAP1298.
It has been mentioned in the datasheet that the CS5 pin be used as a signal guard.
In my PCB, i have included the signal guard around all touchpads on oneside of the board.
Should i place the signal guard on by board's bottom also, or simply is it enough on one side alone?
