(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the
Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may
degrade when the device is not operated under the listed test conditions.
(2) When the input voltage (V
I
) at any pin exceeds power supplies (V
I
< GND or V
I
> V
DD
), the current at that pin should be limited to 5 mA.
(3) The Human Body Model (HBM) is a 100 pF capacitor charged to the specified voltage then discharged through a 1.5 kΩ resistor into
each pin. The Machine Model (MM) is a 200 pF capacitor charged to the specified voltage then discharged directly into each pin. The
Charged Device Model (CDM) is a specified circuit characterizing an ESD event that occurs when a device acquires charge through
some triboelectric (frictional) or electrostatic induction processes and then abruptly touches a grounded object or surface.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the
Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may
degrade when the device is not operated under the listed test conditions.
(2) The junction to ambient temperature resistance (θ
JA
) is specified without a heat sink in still air.
(3) Changes in output due to self heating can be computed by multiplying the internal dissipation by the temperature resistance.

(1) Limits are ensured to AOQL (Average Outgoing Quality Level).
(2) Accuracy is defined as the error between the measured and reference output voltages, tabulated in the Conversion Table at the
specified conditions of supply gain setting, voltage, and temperature (expressed in °C). Accuracy limits include line regulation within the
specified conditions. Accuracy limits do not include load regulation; they assume no DC load.
