NOTES:
1. Accuracy is guaranteed at V_RH − V_RL = 3.3 Vdc ± 0.3V.
2. To obtain full-scale, full-range results, V_SSA ≤ V_RL ≤ V_INDC ≤ V_RH ≤ V_DDA.
3. Maximum leakage occurs at maximum operating temperature. Current decreases by ap-
proximately one-half for each 10°C decrease from maximum temperature.
