12-bit Analog-to-Digital Converter (ADC)

6.18

6.18.1 Overview

The NUC505 series contains one 12-bit successive approximation analog-to-digital converter

(ADC) with 8 single-end external input channels

(ADC_CH0, ADC_CH1, … ADC_CH7). The

ADC_CH0 has an internal 10 k

Ω resistor divider for battery detection. The ADC_CH2 also

supports key pad comparator function. User can control the A/D conversion by setting the

SWTRG (ADC_CTL[0]).
