Comparators are used to interface analog circuits to a
digital circuit by comparing two analog voltages and
providing a digital indication of their relative magnitudes.
The comparators are very useful mixed signal building
blocks because they provide analog functionality
independent of program execution. The Analog
Comparator module includes the following features:
• Independent comparator control
• Programmable input selection
• Comparator output is available internally/externally
• Programmable output polarity
• Interrupt-on-change
• Wake-up from Sleep
• PWM shutdown
• Timer1 gate (count enable)
• Output synchronization to Timer1 clock input
• SR Latch
• Programmable and fixed voltage reference

A single comparator is shown in Figure 8-1 along with
the relationship between the analog input levels and
the digital output. When the analog voltage at V
less than the analog voltage at V
comparator is a digital low level. When the analog
