A simplified circuit for an analog input is shown in
Figure 18-4. 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 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.
