The Analog Comparator module contains two 
comparators that can be configured in a variety of 
ways. 
The following are key features of this module:
• Selectable inputs available include:

- Analog inputs multiplexed with I/O pins
- On-chip internal absolute voltage reference 

(IV

REF

)

- Comparator voltage reference (CV

REF

)

• Outputs can be Inverted
• Selectable interrupt generation
A block diagram of the comparator module is provided 
in 

.

Note 1: This data sheet summarizes the features 

of the PIC32MX330/350/370/430/450/
470 family of devices. It is not intended to 
be a comprehensive reference source.
