562/3748
Up to 5 ADCs, out of which four of them ((in pairs) can operate in dual mode:
ADC1 is connected to 14 external channels + 4 internal channels
ADC2 is connected to 16 external channels + 2 internal channels
ADC3 is connected to 15 external channels + 3 internal channels
ADC4 is connected to 16 external channels + 2 internal channels
ADC5 is connected to 13 external channels + 5 internal channels
12, 10, 8 or 6-bit configurable resolution
ADC conversion time is independent from the AHB bus clock frequency
Faster conversion time by lowering resolution
Manage single-ended or differential inputs
AHB slave bus interface to allow fast data handling
Self-calibration
Channel-wise programmable sampling time
Flexible sampling time control
Up to four injected channels (analog inputs assignment to regular or injected
channels is fully configurable)
Hardware assistant to prepare the context of the injected channels to allow fast
context switching
Data alignment with in-built data coherency
Data can be managed by DMA for regular channel conversions
4 dedicated data registers for the injected channels
16-bit data register
Oversampling ratio adjustable from 2 to 256x
Programmable data shift up to 8-bit
Gain compensation
Offset compensation
