Analog-to-Digital Converter
Introduction
This module explains the operation of the analog-to-digital converter. The system consists of a
12-bit analog-to-digital converter with 16 analog input channels. The analog input channels have
a range from 0 to 3 volts. Two input analog multiplexers are used, each supporting 8 analog input
channels. Each multiplexer has its own dedicated sample and hold circuit. Therefore, sequential,
as well as simultaneous sampling is supported. Also, the ADC system features programmable
auto sequence conversions with 16 results registers. Start of conversion (SOC) can be performed
by an external trigger, software, or an Event Manager event.
