8.2
A single comparator is shown in Figure 8-2 along with
the relationship between the analog input levels and
the digital output. When the analog input at V
than the analog input V
is a digital low level. When the analog input at V
greater than the analog input V
comparator is a digital high level. The shaded areas of
the output of the comparator in Figure 8-2 represent
the uncertainty due to input offsets and response time.
See Table 12-1 for Common Mode Voltage.

An internal reference signal may be used depending on
the comparator operating mode. The analog signal that
is present at V
the digital output of the comparator is adjusted
accordingly (Figure 8-2). Please see Table 12-1 for
internal reference specifications.
8.4
Response time is the minimum time, after selecting a
new reference voltage or input source, before the
comparator output is to have a valid level. If the com-
parator inputs are changed, a delay must be used to
allow the comparator to settle to its new state. Please

specifications.

8.5
The comparator output is read through CMCON0
register. This bit is read-only. The comparator output
may also be used internally, see Figure 8-1.
8.6
The comparator wake-up flag is set whenever all of the
following conditions are met:
• CWU = 0 (CMCON0<0>)
• CMCON0 has been read to latch the last known
• Device is in Sleep
• The output of the comparator has changed state
The wake-up flag may be cleared in software or by
another device Reset.
8.7
When the comparator is active and the device is placed
in Sleep mode, the comparator remains active. While
the comparator is powered-up, higher Sleep currents
than shown in the power-down current specification will
occur. To minimize power consumption while in Sleep
mode, turn off the comparator before entering Sleep.
8.8
A Power-on Reset (POR) forces the CMCON0 register
to its Reset state. This forces the Comparator module
to be in the comparator Reset mode. This ensures that
all potential inputs are analog inputs. Device current is
minimized when analog inputs are present at Reset
time. The comparator will be powered-down during the
Reset interval.
8.9
A simplified circuit for an analog input is shown in
Figure 8-3. Since the analog pins are connected to a
digital output, they have reverse biased diodes to V
and V

range by more than 0.6V in either direction, one of the
diodes is forward biased and a latch-up may occur. A

recommended for the analog sources. Any external
component connected to an analog input pin, such as
a capacitor or a Zener diode, should have very little
leakage current.
