Electrical Characteristics
3.10 Analog-to-Digital Converter Characteristics
Table 24 and Table 25 show conditions under which the ATD operates. The following constraints exist to
obtain full-scale, full range results: V
SS
A
≤
V
RL
≤
V
IN
≤
V
RH
≤
V
DD
A. This constraint exists because the
sample buffer amplifier cannot drive beyond the ATD power supply levels. If the input level goes outside
of this range it will effectively be clipped.
3.10.1 Factors Influencing Accuracy
Three factors — source resistance, source capacitance and current injection
—
have an influence on the
accuracy of the ATD.
