What is the maximum glass thickness that can cover a PCB for Captouch using
AD7142/3 or AD7147/8?
The sensors can operate correctly underneath a covering layer up to a maximum
of 5 mm thick. Recommended thickness is 1 mm to 2 mm. The maximum thickness
also depends on a number of factors like the size of the sensors or the
material of the cover. Please note that we are recommending AD7147/8 for new
designs since these parts provide larger response than the older AD7142/3.
