The total loading of electrode size and capacitance of connecting line on PCB can affect the
sensitivity. So the sensitivity adjustment must according to the practical application on PCB. The
TTP223-BA6/TTP223N-BA6 offers some methods for adjusting the sensitivity outside.
1-1 by the electrode size
Under other conditions are fixed. Using a larger electrode size can increase sensitivity. Otherwise it
can decrease sensitivity. But the electrode size must use in the effective scope.
1-2 by the panel thickness
Under other conditions are fixed. Using a thinner panel can increase sensitivity. Otherwise it can
decrease sensitivity. But the panel thickness must be below the maximum value.
1-3 by the value of Cs (please see the down figure)
Under other conditions are fixed. When do not use the Cs to VSS, the sensitivity is most sensitive.
When adding the values of Cs will reduce sensitivity in the useful range (0≦Cs≦50pF).
