NOTES:
2. Analog input voltages greater than that applied to REF + convert as all ones (111111111111), while input voltages less than that
applied to REF – convert as all zeros (000000000000).
5. Linearity error is the maximum deviation from the best straight line through the A/D transfer characteristics.
6. Gain error is the difference between the actual midstep value and the nominal midstep value in the transfer diagram at the specified
gain point after the offset error has been adjusted to zero. Offset error is the difference between the actual midstep value and the
nominal midstep value at the offset point.
7. Total unadjusted error comprises linearity, zero-scale, and full-scale errors.
8. Both the input address and the output codes are expressed in positive logic.
9. I/O CLOCK period = 1 /(I/O CLOCK frequency) (see Figure 7).
10. Any transitions of CS are recognized as valid only when the level is maintained for a setup time. CS must be taken low at
≤ 5 s
of the tenth I/O CLOCK falling edge to ensure a conversion is aborted. Between 5
s and 10 s, the result is uncertain as to whether
the conversion is aborted or the conversion results are valid.
