* These parameters are characterized but not tested.

Note 1: Settling time measured while VRR = 1 and VR<3:0> transitions from ‘0000’ to ‘1111’.

2: When VDD is between 2.0V and 3.0V, the VREF output voltage levels on RA2 described by the

equation:[VDD/2 ± (3 – VDD)/2] may cause the Absolute Accuracy (VRAA) of the VREF output signal on RA2

to be greater than the stated max.
