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
in series with 100pF.
Note 3:
The maximum power dissipation is a function of T
,
θ
, and T
. The maximum allowable power dissipation at any ambient temperature is

. All numbers apply for packages soldered directly into a PC board.
Note 4:
Typical values represent the most likely parametric norm.
Note 5:
All limits are guaranteed by testing or statistical analysis.
Note 6:
Machine Model, 0
in series with 200pF.
Note 7:
Offset Voltage average drift determined by dividing the change in V
OS
at temperature extremes into the total temperature change.
Note 8:
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 T
J
= T
A
. No guarantee of parametric performance is indicated in the electrical tables under conditions of internal self heating where T
J
>
T
A
.
Absolute Maximum Ratings indicate junction temperature limits beyond which the device may be permanently degraded, either mechanically or electrically.
