10. Capacitive Touch Sense Switches
The capacitive touch sensitive switches on the CapTouchSenseDC are implemented as relaxation oscillators, with
the PCB trace forming the touch-sensitive capacitive element. The relaxation oscillator is constructed using the on-
chip analog comparator, on-chip resistors in the C8051F931 MCU. The on-chip analog multiplexer allows multiple
switches to be operated using one comparator. See Application Note “AN338: Capacitive Touch Sense Solution” at
www.silabs.com
for more information related to the capacitive touch sense switches.
