1. QADC converter specifications are only guaranteed for V DDH and V DDA = 5.0 V ± 0.5 V. V DDH and V DDA may be powered
down to 2.7 V with only GPIO functions supported.
2. To obtain full-scale, full-range results, V SSA ≤ V RL ≤ V INDC ≤ V RH ≤ V DDA
3. Parameter applies to the following pins: Port A: PQA[7:0]/AN[59:58]/ETRIG[2:1]
Port B: PQB[7:0]/AN[3:0]/AN[51:48]/AN[Z:W]
4. Full driver (push-pull)
5. Current measured at maximum system clock frequency with QADC active
6. Maximum leakage occurs at maximum operating temperature. Current decreases by approximately one-half for each 8°C
to 12°C, in the ambient temperature range of –40°C to +85°C.
