22.2
A single comparator is shown in Figure 22-2, along with
the relationship between the analog input levels and
the digital output. When the analog input at V
than the analog input, V
tor is a digital low level. When the analog input at V
is greater than the analog input, V
comparator is a digital high level. The shaded areas of
the output of the comparator in Figure 22-2 represent
the uncertainty due to input offsets and response time.

Response time is the minimum time, after selecting a
new reference voltage or input source, before the
comparator output has a valid level. The response time
of the comparator differs from the settling time of the
voltage reference. Therefore, both of these times must
be considered when determining the total response to
a comparator input change. Otherwise, the maximum
delay of the comparators should be used (see
Section 29.0 “Electrical Characteristics”).
22.4
Figure 22-3 provides a simplified circuit for an analog
input. Since the analog pins are connected to a digital
output, they have reverse biased diodes to V
V
and V
by more than 0.6V in either direction, one of the diodes
is forward biased and a latch-up condition may occur.
A maximum source impedance of 10 kΩ 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.
