NOTES:
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 ± 5% for 20/25 MHz, ± 10% for 16 MHz.
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.
