Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but specific performance is not ensured. For ensured specifications and the test
conditions, see the Electrical Characteristics Tables.

(1)
Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very
limited self-heating of the device such that TJ = TA. No specification of parametric performance is indicated in the electrical tables under
conditions of internal self-heating where TJ > TA.
(2)
All limits are specified by testing, statistical analysis or design.
(3)
Typical values represent the most likely parametric norm at the time of characterization. Actual typical values may vary over time and
will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped production
material.
(4)
Offset voltage temperature drift is determined by dividing the change in VOS at the temperature extremes by the total temperature
change.
(5)
The EMI Rejection Ratio is defined as EMIRR = 20Log ( VRF-PEAK/ΔVOS).
