Typical ratings are not guaranteed. The values listed are at room temperature (+25 C), nominal supply voltages.
Pin capacitance is characterized but not tested.
Including voltage on outputs in 3-state mode.
V
3
supply voltages must be present.
3-state outputs go into 3-state mode when V
3
is grounded.
Accounts for 100 mV voltage drop in all supply lines.
Only allowed for a short time period.
Minimum condition for V
i
= 4.5 V, maximum condition for V
i
= 5.5 V.

The A/D is monotonic, there are no missing codes.
The differential non-linearity (DLe) is the difference between the actual step width and the ideal step width. See
Figure 4
.
The integral no-linearity (ILe) is the peak difference between the center of the steps of the actual and the ideal transfer curve after
appropriate adjustment of gain and offset errors. See
Figure 4
.
The offset error (OSe) is the absolute difference between the straight line which fits the actual curve and the straight line which fits the
ideal curve. See
Figure 4
.
The gain error (Ge) is the relative difference in percent between the straight line fitting the actual transfer curve after removing offset
error, and the straight line which fits the ideal transfer curve. See
Figure 4
.
The absolute voltage error (Ae) is the maximum difference between the center of the steps of the actual transfer curve of the
non-calibrated A/D and the ideal transfer curve. See
Figure 4
.
