Note 1: Response time measured with one comparator input at (V
DD – 1.5)/2, while the other input transitions from
VSS to VDD.
2: These parameters are characterized but not tested.
3: The Comparator module is functional at V
BORMIN < VDD < VDDMIN, but with degraded performance. Unless
otherwise stated, module functionality is guaranteed, but not characterized.
4: CMRR measurement characterized with a 1 M resistor in parallel with a 25 pF capacitor to V
SS.

Note 1: Settling time was measured while CVRR = 1 and CVR<3:0> transitions from ‘0000’ to ‘1111’. This
parameter is characterized, but is not tested in manufacturing.
