* These parameters are characterized but not tested.
† 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: Response time is measured with one comparator input at (V
DD - 1.5)/2 - 100 mV to (VDD -1.5)/2+20mV.
The other input is at (V
DD -1.5)/2.
2: Input offset voltage is measured with one comparator input at (VDD -1.5V)/2.

† 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 8.11 “Comparator Voltage Reference” for more information.
3: Absolute Accuracy when CVREF output is ≤ (VDD-1.5).
