Analog-to-digital converters (ADC1, ADC2 and ADC4)

The devices embed three successive approximation analog-to-digital converters.

3.31.1

Analog-to-digital converters (ADC1/2)

The ADC1/2 are 14-bit ADC successive approximation analog-to-digital converters.

Each ADC has up to 20 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 32-bit data register.

The ADC1/2 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.

A built-in hardware over sampler allows analog performances to be improved while

off-loading the related computational burden from the CPU.

An efficient low-power mode is implemented to allow very low consumption at low

frequency.
