Application note

STM32™’s ADC modes

and their applications

Introduction

STM32 microcontrollers have one of the most advanced ADCs on the microcontroller

market. You could imagine a multitude of applications based on the STM32 ADC features.

Some ADC modes are provided to simplify measurements and give efficient results in

applications such as motor control.

This application note provides help for ADC users to understand some advanced modes

offered in the STM32 microcontrollers, and to quick start development. Each of the

described modes is provided with an example of application to better understand how to use

them. Most modes come with a basic firmware to make it easier to understand the ADC

configuration.

This application note is divided into two sections: independent modes and dual modes. The

first section describes modes used with a single ADC. The second section describes modes

that should be used with two ADCs (ADC1 and ADC2 working jointly).

This application note does not describe the ADC modes that result from the combination of

other modes.
