A.2 ATD Characteristics
This section describes the characteristics of the analog to digital converter.
A.2.1 ATD Operating Characteristics
The
Table A-8
shows conditions under which the ATD operates.
The following constraints exist to obtain full-scale, full range results:
V
SSA
V
RL
V
IN
V
RH
V
DDA
.
This constraint exists since the sample buffer amplifier can not drive
beyond the power supply levels that it ties to. If the input level goes outside of this range it will effectively
be clipped.
Table A-8 ATD Operating Characteristics
A.2.2 Factors influencing accuracy
Three factors – source resistance, source capacitance and current injection – have an influence on the
accuracy of the ATD.
A.2.2.1 Source Resistance:
Due to the input pin leakage current as specified in
Table A-6
in conjunction with the source resistance
there will be a voltage drop from the signal source to the ATD input. The maximum source resistance R

NOTES
:
1. Full accuracy is not guaranteed when differential voltage is less than 4.50V
2. The minimum time assumes a final sample period of 2 ATD clocks cycles while the maximum time assumes a final sample
period of 16 ATD clocks.
