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, 1.5k

Note 3:
Machine model, 0
in series with 200pF.
Note 4:
The maximum power dissipation is a function of T

. All numbers apply for packages soldered directly onto a PC board.
Note 5:
Typical values represent the most likely parametric norm.
Note 6:
All limits are guaranteed by testing or statistical analysis.
Note 7:
The input common-mode voltage of either input should not be permitted to go below the negative rail by more than 0.3V. The upper end of the
common-mode voltage range is V
