Electrical Characteristics
3.10.2 ATD Accuracy
Table 27 and Table 28 specify the ATD conversion performance excluding any errors due to current
injection, input capacitance and source resistance.
For the following definitions see also Figure 8.
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:
Table 27. ATD Conversion Performance in 5 V Range
Conditions shown in Table 6 unless otherwise noted.
VREF = VRH – VRL = 5.12 V, resulting in one 8 bit count = 20 mV and one 10 bit count = 5 mV
fATDCLK = 2.0 MHz, 4.5 V ≤ VDDA ≤ 5.5 V
