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
beyond the power supply levels that it ties to. If the input level goes outside of this range it will effectively
be clipped.
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
Conditions are shown in Table A-4 unless otherwise noted
Num C
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
