Analog-to-digital converter (ADC1)4.13
The STM8S105xx products contain a 10-bit successive approximation A/D converter (ADC1)
with up to 10 multiplexed input channels and the following main features:
•
Input voltage range: 0 to V
DDA
•
Conversion time: 14 clock cycles
•
Single and continuous and buffered continuous conversion modes
•
Buffer size (n x 10 bits) where n = number of input channels
•
Scan mode for single and continuous conversion of a sequence of channels
•
Analog watchdog capability with programmable upper and lower thresholds
•
Analog watchdog interrupt
•
External trigger input
•
Trigger from TIM1 TRGO
•
End of conversion (EOC) interrupt
Note: Additional AIN12 analog input is not selectable in ADC scan mode or with analog
watchdog. Values converted from AIN12 are stored only into the ADC_DRH/ADC_DRL
registers.
