Analog Input Connection
Considerations
A simplified circuit for an analog input is shown in
Figure 6-3. Since the analog pins are connected to a
digital output, they have reverse biased diodes to VDD
and VSS. The analog input, therefore, must be between
VSS and VDD. If the input voltage deviates from this
range by more than 0.6V in either direction, one of the
diodes is forward biased and a latch-up may occur. A
maximum
source
impedance
of
10 k
is
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.

ANALOG INPUT MODE

Comparator Output
The comparator output, COUT, is read through the
CMCON register. This bit is read-only. The comparator
output may also be directly output to the RA2 pin in
three of the eight possible modes, as shown in
Figure 6-2. When in one of these modes, the output on
RA2 is asynchronous to the internal clock. Figure 6-4
shows the comparator output block diagram.
The TRISA<2> bit functions as an output enable/
disable for the RA2 pin while the comparator is in an
Output mode.

Note 1: When reading the PORTA register, all
pins configured as analog inputs will read
as a ‘0’. Pins configured as digital inputs
will convert an analog input according to
the TTL input specification.
2: Analog levels on any pin that is defined as
a digital input, may cause the input buffer
to consume more current than is
specified.
