NOTES:
1. Refers to operation over full temperature and frequency range.
2. To obtain full-scale, full-range results, V_SSA ≤ V_RL ≤ V_INDC ≤ V_RH ≤ V_DDA.
3. Accuracy tested and guaranteed at V_RH – V_RL = 2.7 V ± 3.6 Vdc.
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.
