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.
LPC2294 only.

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
.
