9.2
A simplified circuit for an analog input is shown in
Figure 9-3. Since the analog input pins share their
connection with a digital input, they have reverse
biased ESD protection diodes to V
analog input, therefore, must be between V
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. Also, any
external component connected to an analog input pin,
such as a capacitor or a Zener diode, should have very
little
introduced.
