2021-11-18
Introduction:
●In order to obtain proper function when using touch sensors, certain design guidelines must be followed for the application circuit and the design of sensor plates.
●This application note considers the typical application circuit on a pin-by-pin basis and recommends appropriate components.
●A theoretical background for the design of sensor plates is given and applies also on sliders and key matrices.
