NOTES:
3. Analog input voltages greater than that applied to REFP convert as all ones (1111111111), while input voltages less than that applied
to REFM convert as all zeros (0000000000). The device is functional with reference down to 2 V (VREFP – VREFM); however, the
electrical specifications are no longer applicable.
4. Linear error is the maximum deviation from the best straight line through the A/D transfer characteristics.
5. Zero error is the difference between 0000000000 and the converted output for zero input voltage: full-scale error is the difference
between 1111111111 and the converted output for full-scale input voltage.
6. Total unadjusted error comprises linearity, zero, and full-scale errors.
7. Both the input data and the output codes are expressed in positive logic.
