Note 1 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 guaranteed For guaranteed specifications and the test conditions see the Electrical Characteristics
Note 2 Human body model 1 5 k
Note 3 Applies to both single-supply and split-supply operation Continuous short circuit operation at elevated ambient temperature can result in exceeding the
maximum allowed junction temperature of 150 C
Note 4 The maximum power dissipation is a function of T
(T
Note 5 Typical Values represent the most likely parametric norm
Note 6 All limits are guaranteed by testing or statistical analysis
Note 7 Differential input voltage is measured at V
