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.

Table B-6 ATD Conversion Performance

Conditions are shown in Table A-4 unless otherwise noted

VREF = VRH - VRL = 5.12V. Resulting to one 8 bit count = 20mV and one 10 bit count = 5mV

fATDCLK = 2.0MHz
