Analog-to-digital converter (ADC)

11.1

ADC introduction

The 12-bit ADC is a successive approximation analog-to-digital converter. It has up to 19
multiplexed channels allowing it to measure signals from 16 external sources, two internal
sources, and the V
single, continuous, scan or discontinuous mode. The result of the ADC is stored into a left-
or right-aligned 16-bit data register.
The analog watchdog feature allows the application to detect if the input voltage goes
beyond the user-defined, higher or lower thresholds.

ADC main features

•
12-bit, 10-bit, 8-bit or 6-bit configurable resolution
• Interrupt generation at the end of conversion, end of injected conversion, and in case of
analog watchdog or overrun events
•
Single and continuous conversion modes
•
Scan mode for automatic conversion of channel 0 to channel 'n'
•
Data alignment with in-built data coherency
•
Channel-wise programmable sampling time
•
External trigger option with configurable polarity for both regular and injected
conversions
•
Discontinuous mode
•
Configurable delay between conversions in Dual/Triple interleaved mode
•
ADC supply requirements: 2.4 V to 3.6 V at full speed and down to 1.8 V at slower
speed
• ADC input range: V
•
DMA request generation during regular channel conversion
