Application note
How to improve ADC accuracy when using STM32F2xx and
STM32F4xx microcontrollers
Introduction
The purpose of this application note is to show how to improve the accuracy of A/D
conversions for applications using the STM32F2xx and STM32F4xx microcontrollers.
It also explains the firmware methodology, which can be applied to reduce the ADC error
and gives some general tips on writing firmware for better ADC accuracy.
Please note that the data provided with this application note is for reference only, measured
in a lab under typical conditions (unless specified otherwise) and not tested in production.
Table 1 lists the microcontrollers concerned by this application note.
