QADC converter specifications are only guaranteed for VDDH and VDDA = 5.0V +/- 0.5V. VDDH and VDDA may be
powered down to 2.7V with only GPIO functions supported.

Parameter applies to the following pins:
Port A: PQA[4:3]/AN[56:55]/ETRIG[2:1], PQA[1:0]/AN[53:52]/MA[1:0]
Port B: PQB[3:0]/AN[3:0]/AN[Z:W]
4
Current measured at maximum system clock frequency with QADC active.
5
Maximum leakage occurs at maximum operating temperature. Current decreases by approximately one-half for each 8
to 12° C, in the ambient temperature range of 50 to 125 °C.
6
This parameter is characterized before qualification rather than 100% tested.
