Note 1: Response time measured with one comparator input at (V
DD – 1.5)/2, while the other input transitions
from V
SS to VDD.
2: These parameters are characterized but not tested.
3: Settling time measured while CVRR = 1 and CVR<3:0> transitions from ‘0000’ to ‘1111’. This parameter is
characterized, but not tested in manufacturing.
