Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended 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 kΩ in series with 100 pF.
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. Output currents in excess of
±
30 mA over long term may adversely affect reliability.
Note 4:
The maximum power dissipation is a function of T
J(max)
,
θ
JA
, and T
A
. The maximum allowable power dissipation at any ambient temperature is
P
D
= (T
J(max)
− T
A
)/θ
JA
.All numbers apply for packages soldered directly into 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:
Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage rating.
Note 8:
Do not short circuit output to V+, when V+ is greater than 12V or reliability will be adversely affected.
Note 9:
C
L
includes the probe and jig capacitance.
Note 10:
Input offset voltage average drift is calculated by dividing the accelerated operating life V
OS
drift by the equivalent operational time. This represents worst
case input conditions and includes the first 30 days of drift.
Note 11:
Input step voltage for propagation delay measurement is 2V.
