A.2.4 ATD accuracy
A.2.4.1 5V Range
Table A-13 specifies the ATD conversion performance excluding any errors due to current injection,
input capacitance and source resistance.
Table A-13 ATD Conversion Performance In 5V Range
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
Supply Voltage 5V-10% <= V_DDA <=5V+10%
