15.3.4 Analog-to-Digital Converter
The Analog-to-Digital Converter (ADC) module uses a Successive Approximation Register (SAR)
architecture to deliver a 12-bit, low-power, high-precision conversion value. The successive
approximation uses a switched capacitor array to perform the dual functions of sampling and holding
the signal as well as providing the 12-bit DAC operation.
Figure 15-7 shows the ADC input equivalency diagram; for parameter values, see “Analog-to-Digital
Converter (ADC)” on page 1861.
