Typical ratings are not guaranteed. The values listed are at room temperature (25 ° C), nominal supply voltages.
Including voltage on outputs in 3-state mode.
V DD(3V3) and V DD(IO) supply voltages must be present.
3-state outputs go into 3-state mode when V DD(IO) is grounded.
Accounts for 100 mV voltage drop in all supply lines.
Allowed as long as the current limit does not exceed the maximum current allowed by the device.

Typical ratings are not guaranteed. The values listed are at room temperature (25 ° C), nominal supply voltages.
Conditions: V SS = 0 V, V DD (3V3) = 3.3 V.
The ADC is monotonic, there are no missing codes.
The differential linearity error (E D ) is the difference between the actual step width and the ideal step width. See Figure 7 .
The integral non-linearity (E L(adj) ) is the peak difference between the center of the steps of the actual and the ideal transfer curve after
The offset error (E O ) is the absolute difference between the straight line which fits the actual curve and the straight line which fits the
The gain error (E G ) is the relative difference in percent between the straight line fitting the actual transfer curve after removing offset
The absolute error (E T ) is the maximum difference between the center of the steps of the actual transfer curve of the non-calibrated
