(1) All typical values are at VCC = 5 V, TA = 25°C.
(2) Analog input voltages greater than the voltage applied to REF+ convert as all ones (111111111111), while input voltages less than the voltage applied to REF– convert as all zeros (000000000000).
(3) Linearity error is the maximum deviation from the best straight line through the A/D transfer characteristics.
(4) 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.
(5) Total unadjusted error comprises linearity, zero-scale errors, and full-scale errors.
(6) Both the input address and the output codes are expressed in positive logic.
