Comparator Hysteresis

Each comparator has built-in hysteresis that is user

enabled by setting the C1HYS or C2HYS bits of the

CM2CON1 register. The hysteresis feature can help

filter noise and reduce multiple comparator output

transitions when the output is changing state.

Figure 8-9 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-).
