(1) Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating range indicates conditions for which
the device is intended to be functional, but does not ensure specific performance limits. For ensured specifications and test conditions
see 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) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3) VDDQ voltage must be less than 2 x (AVIN - 1) or 6V, whichever is smaller.
(4) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.

(1) Limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlation using
Statistical Quality Control (SQC) methods. The limits are used to calculate Average Outgoing Quality Level (AOQL).
