NOTES:
1. VDD = 3.3 Vdc ±10%, VSS = 0 Vdc, TA = 0 °C to +70 °C, unless otherwise noted
2. The comparator is guaranteed to function over the specied 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 specications; for example, SR, tCOMP, and VOFF.
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.
