3.10.2 ATD Accuracy
Table 29 and Table 30 specify the ATD conversion performance excluding any errors due to current
injection, input capacitance and source resistance.
For the following definitions, see Figure 9.
Differential Non-Linearity (DNL) is defined as the difference between two adjacent switching steps:
Eqn. 17
The Integral Non-Linearity (INL) is defined as the sum of all DNLs:
Eqn. 18
