Application note
Precision improvement techniques
for the A/D converter of the STM8 microcontroller
Introduction
This application note describes a selection of hardware and software methods for improving
the precision of the on-chip A/D converter of the STM8 microcontroller (STM8 ADC). It is
divided into three sections:
■ The first section explains the internal design principle of the STM8 ADC.
■ The next section lists the main types of error that occur in A/D converters and their
sources.
■ The last section describes some hardware and software methods for minimizing these
errors.
Firmware examples (source codes) are provided with this application note showing how to
implement STM8 ADC routines for minimizing measurement errors.
