A single comparator is shown in Figure 12-2 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 12-2 represent
the uncertainty due to input offsets and response time.
12.3
An external or internal reference signal may be used
depending on the comparator operating mode. The
analog signal present at V
at V
adjusted accordingly (Figure 12-2).
FIGURE 12-2:
12.3.1
When external voltage references are used, the
comparator module can be configured to have the com-
parators operate from the same or different reference
sources. However, threshold detector applications may
require the same reference. The reference signal must
be between V
pin of the comparator(s).

The comparator module also allows the selection of an
internally generated voltage reference for the compara-
tors. Section 13.0 “Comparator Voltage Reference
Module” contains a detailed description of the Compar-
ator Voltage Reference module that provides this signal.
The internal reference signal is used when comparators
are in mode, CM<2:0> = 110 (Figure 12-1). In this
mode, the internal voltage reference is applied to the
V
12.4
Response time is the minimum time, after selecting a
new reference voltage or input source, before the com-
parator output has a valid level. If the internal reference
is changed, the maximum delay of the internal voltage
reference must be considered when using the compar-
ator outputs. Otherwise, the maximum delay of the
comparators should be used (Section 17.0 “Electrical
Characteristics”).
12.5
The comparator outputs are read through the CMCON
register. These bits are read-only. The comparator
outputs may also be directly output to the RA4 and RA5
I/O pins. When enabled, multiplexors in the output path
of the RA4 and RA5 pins will switch and the output of
each pin will be the unsynchronized output of the com-
parator. The uncertainty of each of the comparators is
related to the input offset voltage and the response time
given in the specifications. Figure 12-3 shows the
comparator output block diagram.
The TRISA bits will still function as an output enable/
disable for the RA4 and RA5 pins while in this mode.
The polarity of the comparator outputs can be changed
using the C2INV and C1INV bits (CMCON<4:5>).
