Introduction

STM32H7 Series MCUs embed three successive-approximation-register (SAR) ADCs with 16-bit resolution targetting

applications requiring high accuracy measurements and high data rates.

This application note describes the new features and performance figures of the 16-bit ADC.

It explains how the ADC performance varies under various conditions, and provides guidelines to exploit the full potential of the

STM32 16-bit ADC.

This document applies to the STM32H7 Series product lines listed in Table 1.
