NOTES: 3. Analog input voltages greater than that applied to VREF convert as all ones (111111111111).
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 000000000000 and the converted output for zero input voltage: full-scale error is the difference
between 111111111111 and the converted output for full-scale input voltage.
6. Total unadjusted error comprises linearity, zero, and full-scale errors.
