Introduction
2.5.8 Analog-to-Digital Converters
The TC1797 includes three Analog to Digital Converter modules (ADC0, ADC1, ADC2)
and one Fast Analog to Digital Converter (FADC).
2.5.8.1 ADC Block Diagram
The analog to digital converter module (ADC) allows the conversion of analog input
values into discrete digital values based on the successive approximation method.
This module contains 3 independent kernels (ADC0, ADC1, ADC2) that can operate
autonomously or can be synchronized to each other. An ADC kernel is a unit used to
convert an analog input signal (done by an analog part) and provides means for
triggering conversions, data handling and storage (done by a digital part).
