NOTES:
1. V_DD = 3.3 Vdc ±10%, V_SS = 0 Vdc, TA = 0 °C to +70 °C, unless otherwise noted
2. The comparator is guaranteed to function over the specified input voltage range with no erroneous outputs.
3. Signal propagation time through the comparators measured with 100 mv of overdrive.
4. Comparator is guaranteed to meet specifications; for example, SR, t_COMP, and V_OFF.
5. Input offset voltage is guaranteed over the temperature range.
6. Enable time is the time from enabling the comparator with the CEN bit until the comparator is fully functional.
