Application note

Implementing a simple ADC

using the STM8L101xx comparator

Introduction

This application note gives a simple method for implementing an A/D converter with a

minimum amount of external components: one resistor and one capacitor.

The pratical application example described in this document uses the STM8L101xx

microcontroller comparator.
