Appendix A Electrical Characteristics
A.6.4 ATD Accuracy — 5V Range
Table A-22 specifies the ATD conversion performance excluding any errors due to current injection, input
capacitance and source resistance.
Table A-22. 5V ATD Conversion Performance
Conditions are shown in Table A-4 unless otherwise noted
V_REF = V_RH - V_RL = 5.12V. Resulting to one 8 bit count = 20mV and one 10 bit count = 5mV
f_ATDCLK = 2.0MHz
