12. Module: Analog-to-Digital Converter

At the beginning of sample acquisition, one or
more small pull-up pulses (approximately 25 ns
long) may output to the currently selected ANx
analog channel. These pulses can lead to a pos-
itive offset error when the analog signal voltage
is near V
is unable to dissipate the added pull-up voltage
before the A/D conversion occurs.
Work around
Do one or more of the following:
• Use the “0 T
• Use a longer A/D Acquisition Time setting to
• Use low-impedance, active analog signal
• Experiment with external filter capacitor

to start the next sample acquisition period
immediately following A/D conversion
completion.
This allows the external analog signal driver
more time to dissipate the pull-up pulses that
occur when the sample acquisition is started.
provide time for the external analog signal
driver to dissipate the pull-up pulse voltage.
drivers to reduce the time needed to dissipate
the pull-up pulse voltage.
values to avoid allowing the pull-up voltage
offset to affect the final voltage that gets
converted.
Small filter capacitor values (or none at all) will
allow time for the external analog signal driver
to dissipate the pull-up voltage quickly. Alter-
nately, large filter capacitor values will prevent
the short pull-up pulses from increasing the
final voltage enough to cause A/D conversion
error.
