Comparator Hysteresis

Each comparator has built-in hysteresis that is user

enabled by setting the CMHYS bit of the CMCON1

reduce multiple comparator output transitions when the

output is changing state.

Figure 9-7 shows the relationship between the analog

input levels and digital output of a comparator with and

without hysteresis. The output of the comparator

changes from a low state to a high state only when the

analog voltage at VIN+ rises above the upper

hysteresis

threshold

(VH+).

The

output

the

comparator changes from a high state to a low state

only when the analog voltage at VIN+ falls below the

lower hysteresis threshold (VH-).
