8.7
A simplified circuit for an analog input is shown in
Figure 8-6. Since the analog input pins share their con-
nection with a digital input, they have reverse biased
ESD protection diodes to V
input, therefore, must be between V
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 kΩ 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 leakage current to
minimize inaccuracies introduced.
