(1) Absolute Maximum Ratings indicate limits beyond which damage may occur. Recommended Operating Conditions indicate conditions
for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and test
conditions, see Electrical Characteristics.
(2) The maximum power dissipation is a function of TJ(MAX), θJA. The maximum allowable power dissipation at any ambient temperature
is PD = (TJ(MAX) – TA)/ θJA. All numbers apply for packages soldered directly onto a PC Board.

(1) Electrical Characteristics 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 guarantee of parametric performance is indicated in the electrical tables
under conditions of internal self-heating where TJ TA. Absolute Maximum Ratings indicate junction temperature limits beyond which the
device may be permanently degraded, either mechanically or electrically.
(2) The offset voltage average drift is determined by dividing the change in VOS at the temperature extremes by the total temperature
change.
