Application note
Capacitor selection guide for STM8T141
capacitive sensor
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 (C
S
) for their applications by investigating the most important
undesirable characteristics. For STM8T141 devices, the specific power mode selected and
the proximity sensitivity will also directly influence this decision.
