2.8 A/D (Analog-to-Digital) Converter
Onboard ADC is an 11-bit, 100kS/s analog-to-digital converter. This ADC adopts successive
approximation register (SAR) architecture which using a 9-bit charge scaling sub-DAC for MSB
and a 2-bit voltage scaling sub-DAC for LSB. The input range is between 0 and VCCA (3.3V).
