1. Refers to operation over full temperature and frequency range.
2. To obtain full-scale, full-range results, VSSA ≤ VRL ≤ VINDC ≤ VRH ≤ VDDA.
3. Accuracy tested and guaranteed at VRH VRL ≤ 5.0 V ± 10%.
4. Current measured at maximum system clock frequency with ADC active.
5. Maximum leakage occurs at maximum operating temperature. Current decreases by approximately
one-half for each 10
°C decrease from maximum temperature.
1. Conversion accuracy varies with fADCLK rate. Reduced conversion accuracy occurs at maximum.
