Note 2. Accuracy is the difference between the output code when 5 volts is input to the VBAT pin and the “ideal” code at 1.25
volts.
Note 3. “Ideal” value derived from theory
Note 4. Accuracy is defined as the difference between the voltage measured by two current sources, and the ideal voltage derived
from theory at specific temperatures.
