PIC24FJ128GA010 FAMILY
21.0 COMPARATOR MODULE
Note:
This data sheet summarizes the features
of this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. Refer to Section 19. “Compara-
tor Module” (DS39710) in the “PIC24F
Family Reference Manual” for more
information.
The analog comparator module contains two
comparators that can be configured in a variety of
ways. The inputs can be selected from the analog
inputs multiplexed with I/O pins, as well as the on-chip
voltage reference. Block diagrams of the various
comparator configurations are shown in Figure 21-1.
