1QADC 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.

2To obtain full-scale, full-range results, VSSA ≤ VRL ≤ VINDC ≤ VRH ≤ VDDA

3Parameter 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]

4Current measured at maximum system clock frequency with QADC active.

5Maximum 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.

6This parameter is characterized before qualification rather than 100% tested.
