Introduction

This section describes the implementation of up to 2 ADCs:
ADC1 and ADC2 are tightly coupled and can operate in dual mode (ADC1 is master).
Each ADC consists of a 12-bit successive approximation analog-to-digital converter.
Each ADC has up to 19 multiplexed channels. A/D conversion of the various channels can
be performed in single, continuous, scan or discontinuous mode. The result of the ADC is
stored in a left-aligned or right-aligned 16-bit data register.
The ADCs are mapped on the AHB bus to allow fast data handling.
The analog watchdog features allow the application to detect if the input voltage goes
outside the user-defined high or low thresholds.
An efficient low-power mode is implemented to allow very low consumption at low
frequency.
Note: The STM32F302x6/8 devices have only ADC1. The STM32F302xB/C/D/E have ADC1 and
ADC2.
