1. VDD = 5.0 Vdc Â± 10%, VSS = 0 Vdc, TA = TL to TH, ATD clock = 2 MHz, unless otherwise noted

2. Accuracy is guaranteed at VRH â VRL = 5.0 Vdc Â± 10%.

3. To obtain full-scale, full-range results, VSSA â¤ VRL â¤ VINDC â¤ VRH â¤ VDDA.

4. Maximum leakage occurs at maximum operating temperature. Current decreases by approximately one-half for each

10 Â°C decrease from maximum temperature.
