Chapter 8 Analog-to-Digital Converter (S08ADC10V1)
9.1.2 Features
Features of the ADC module include:
⢠Linear successive approximation algorithm with 10-bit resolution
⢠Up to 28 analog inputs1
⢠Output formatted in 10- or 8-bit right-justiï¬ed unsigned format
⢠Single or continuous conversion (automatic return to idle after single conversion)
⢠Conï¬gurable sample time and conversion speed/power
⢠Conversion complete ï¬ag and interrupt
⢠Input clock selectable from up to four sources
⢠Operation in wait or stop3 modes for lower noise operation
⢠Asynchronous clock source for lower noise operation
⢠Selectable asynchronous hardware conversion trigger
⢠Automatic compare with interrupt for less-than, or greater-than or equal-to, programmable value
9.1.3 ADC Module Block Diagram
Figure 9-2 provides a block diagram of the ADC module
1. Number of analog inputs varies according to the device and may be from external or internal sources. Refer to the introduction
section to this chapter for AD0âAD27 channel input assignments.
