Appendix A Electrical Characteristics
A.2
This section describes the characteristics of the analog to digital converter.
A.2.1
The
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
Three factors – source resistance, source capacitance and current injection – have an influence on the
accuracy of the ATD.
A.2.2.1
Due to the input pin leakage current as specified in
there will be a voltage drop from the signal source to the ATD input. The maximum source resistance R
specifies results in an error of less than 1/2 LSB (2.5mV) at the maximum leakage current. If device or
operating conditions are less than worst case or leakage-induced error is acceptable, larger values of source
resistance is allowed.

Num C
Full accuracy is not guaranteed when differential voltage is less than 4.50V
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.
