Comparator Operation

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 input at VIN+ is less than the analog input VIN-, the output of the comparator is a digital low level. When the analog input at VIN+ is greater than the analog input VIN-, the output of the comparator is a digital high level. The shaded areas of the output of the comparator in Figure 8-1 represent the uncertainty due to input offsets and response time

Comparator Configuration There are eight modes of operation for the comparators. The CMCON0 register is used to select these modes. Figure 8-3 shows the eight possible modes.

If the Comparator mode is changed, the comparator output level may not be valid for the specified mode change delay shown in Section 15.0 “Electrical Specifications”
