Conclusion

As explained, the sampling capacitor characteristics play an important role in the correct

and stable operation of a capacitive sensing application. Consequently, it is necessary to

select it carefully.

The recommendations for the STM8T141 capacitive sensor are summarized below:

•

When the STM8T141 low power modes with zoom are used, PET, PEN, PPS or NPO

capacitor types must be used.

•

If the STM8T141 is used for proximity detection, PET, PEN, PPS or NPO capacitor

types should be used.

•

If the STM8T141 is used for touch detection, all capacitor types except tantalum can be

used.
