† Data in “Typ” column is at 5V, 25°C unless otherwise stated. These parameters are for design
guidance only and are not tested.
Note 1: Settling time measured while VRR = 1 and VR<3:0> transitions from ‘0000’ to ‘1111’.
2: See Section 9.10 “Comparator Voltage Reference” for more information.
3: Absolute Accuracy when CVREF output is (VDD -1.5).
