Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC andAC electrical specifications do not apply when operating
the device beyond its specified operating conditions.
Note 2: All voltages are measured with respect to the GND pin, unless otherwise specified.
Note 3: Total unadjusted error includes offset, full-scale, and linearity errors.
Note 4: Accuracy may degrade if t
WR
or t
RD
is shorter than the minimum value specified. See Accuracy vs t
WR
and Accuracy vs t
RD
graphs.
Note 5: When the input voltage (V
IN
) at any pin exceeds the power supply rails (V
IN
<
V
−
or V
IN
>
V
+
) the absolute value of current at that pin should be limited to
1 mA or less. The 4 mA package input current limits the number of pins that can exceed the power supply boundaries witha1mAcurrent limit to four.
Note 6: Typicals are at 25˚C and represent most likely parametric norm.
Note 7: Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 8: Design limits are guaranteed but not 100
%
tested. These limits are not used to calculate outgoing quality levels.
Note 9: Human body model, 100 pF discharaged through a 1.5 kΩ resistor.
