Application note
Sampling capacitor selection guide for MCU based touch sensing
applications
Note:
Introduction
Capacitors feature some non-ideal characteristics that unfortunately limit their use in certain
applications. The objective of this application note is to help designers in selecting the right
sampling capacitor (CS) for their touch sensing applications by investigating the most
important undesirable characteristics.
STMicroelectronics is providing free STMTouch touch sensing firmware libraries which are
available either as standalone packages (STM8L-TOUCH-LIB) or directly integrated into the
corresponding STM32Cube package (STM32CubeL0, STM32CubeF0, â¦).
