NOTES:
2. Analog input voltages greater than that applied to REF + convert as all ones (1111111111), while input voltages less than that applied
to REF convert as all zeros (0000000000). The device is functional with reference voltages down to 1 V (Vref + Vref ); however,
the electrical specifications are no longer applicable.
6. Linearity error is the maximum deviation from the best straight line through the A/D transfer characteristics.
7. Zero-scale 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.
8. Total unadjusted error comprises linearity, zero-scale, and full-scale errors.
9. Both the input address and the output codes are expressed in positive logic.
10. I/O CLOCK period = 1/(I/O CLOCK frequency) (see Figure 6)
