Analog to Digital Converter

The Analog to Digital Converter module (ADC) of the XC2000 allows the conversion of

analog input values into discrete digital values based on the successive approximation

method. With this method, the conversion result is elaborated bit by bit, starting with the

most significant bit. As a consequence, an analog to digital conversion requires a certain

number of clock cycles.

This chapter is structured as follows:

•

Introduction (see Section 16.1)

•

Operating the ADC (see Section 16.2)

•

Module implementation in XC2000 (see Section 16.3)
