NOTES:

1.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.

B.4.3 Factors influencing accuracy

Three factors - source resistance, source capacitance and current injection - have an influenceon the accuracy of the ATD.

B.4.3.1 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 RS 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 allowable.

B.4.3.2 Source capacitance

When sampling an additional internal capacitor is switched to the input. This can cause a voltage drop due to charge sharing with the external and the pin capacitance. For a maximum sampling error of the input voltage ≤ 1LSB, then the external filter capacitor, Cf ≥ 1024 * (CINS- CINN).
