A.2.3.2 3.3V Range

Table A-14 specifies the ATD conversion performance excluding any errors due to current injection,

input capacitance and source resistance.

A.2.3.3 ATD Accuracy Definitions

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:

NOTES:

1. These values include the quantization error which is inherently 1/2 count for any A/D converter.

Table A-14 ATD Conversion Performance 3.3V

Conditions are shown in Table A-4 unless otherwise noted

VREF = VRH - VRL = 3.328V. Resulting to one 8 bit count = 13mV and one 10 bit count = 3.25mV

fATDCLK = 2.0MHz
