Note:
If the comparator input voltage is not equal to VDD or VSS, there may be more IDD/ISTB current consumed by the
pin-shared logic input function whether the comparator is enabled or disabled.
Typically, the current for each comparator input pin is about 500mA (VDD=5V) if its input voltage is 2.5V.
