A.2.3 ATD accuracy

(Table A-10) specifies the ATD conversion performance excluding any errors due to current injection,

input capacitance and source resistance.

Table A-10 ATD Conversion Performance

For the following definitions see also Figure A-1.

Differential Non-Linearity (DNL) is defined as the difference between two adjacent switching steps.

The Integral Non-Linearity (INL) is defined as the sum of all DNLs:

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
