B.4.4 ATD accuracy (5V Range)
Table B-6 specifies the ATD conversion performance excluding any errors due to current injection, input
capacitance and source resistance.
B.4.5 ATD accuracy (3.3V Range)
Table B-6 specifies the ATD conversion performance excluding any errors due to current injection, input
capacitance and source resistance.
