Analog-to-digital converter (ADC1)

4.13

The STM8S103xx family products contain a 10-bit successive approximation A/D converter

(ADC1) with up to 5 external multiplexed input channels and the following main features:

• Input voltage range: 0 to VDD

• 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
