TS01

　　APPLICATION SUMMARY Sensitivity adjustment 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 TS01A 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）。
