MOTOROLA
The external circuit described in
Measurements of an AC component of the external signal must take the
characteristics of this filter into account.
A series resistor limits the current to a pin therefore, input leakage acting
through a large source impedance can degrade A/D accuracy. The
maximum input leakage current is specified in
Electrical Specifications
higher operating temperatures. In the temperature range from 125°C to
50°C, the leakage current is halved for every 8°C to 12°C reduction in
temperature.
Assuming V
corresponds to 5 mV of input voltage. A typical input leakage of 200 nA
acting through 10 k of external series resistance results in an error of
0.4 count (2.0 mV). If the source impedance is 100 k
leakage of 100 nA is present, an error of 2 counts (10 mV) is introduced.
In addition to internal junction leakage, external leakage (for example, if
external clamping diodes are used) and charge sharing effects with
internal capacitors also contribute to the total leakage current.

terms of 10-bit counts.
