[1]

Typical ratings are not guaranteed. The values listed are at room temperature (+25 ˚C), nominal supply voltages. Pin capacitance is

characterized but not tested.

[2]

Including voltage on outputs in 3-state mode.

[3]

V3 supply voltages must be present.

[4]

3-state outputs go into 3-state mode when V3 is grounded.

[5]

Accounts for 100 mV voltage drop in all supply lines.

[6]

Only allowed for a short time period.

[7]

Minimum condition for Vi = 4.5 V, maximum condition for Vi = 5.5 V.

[1]

Conditions: VSSA =0V, V3A = 3.3 V.

[2]

The A/D is monotonic, there are no missing codes.

[3]

The differential non-linearity (DLe) is the difference between the actual step width and the ideal step width. See Figure 4.

[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.

[5]

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.

[6]

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.

[7]

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.
