The Comparator module provides a set of dual input 
comparators. The inputs to the comparator can be 
configured to use any one of the four pin inputs 
(C1IN+, C1IN-, C2IN+ and C2IN-) as well as the 
Comparator Voltage Reference Input (CV

REF

).

Note 1: This data sheet summarizes the features 

of the dsPIC33FJ32MC302/304, 
dsPIC33FJ64MCX02/X04 and 
dsPIC33FJ128MCX02/X04 family of 
devices. It is not intended to be a 
comprehensive reference source. To 
complement the information in this data 
sheet, refer to Section 34. 
“Comparator” (DS70212) of the 
“dsPIC33F/PIC24H Family Reference 
Manual”, which is available from the
