• Start-of-conversion can be initiated:
– by software for both regular and injected conversions
– by hardware triggers with configurable polarity (internal timers events or GPIO
input events) for both regular and injected conversions
• Conversion modes
– Each ADC can convert a single channel or can scan a sequence of channels
– Single mode converts selected inputs once per trigger
– Continuous mode converts selected inputs continuously
– Discontinuous mode
• Dual ADC mode for ADC1 and 2
• Interrupt generation at ADC ready, the end of sampling, the end of conversion (regular
or injected), end of sequence conversion (regular or injected), analog watchdog 1, 2 or
3 or overrun events
• 3 analog watchdogs per ADC
• ADC supply requirements: 1.62 to 3.6 V
• ADC input range: V
