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:
Do not short circuit output to V
+
, when V
+
is greater than 12V or reliability will be adversely affected.
Note 8:
Input Offset Voltage Average Drift is calculated by dividing the accelerated operating life drift average by the equivalent operational time. The Input Offset
Voltage Average Drift represents the input offset voltage change at worst-case input conditions.
Note 9:
C
L
includes the probe and jig capacitance.
Note 10:
The rise and fall times are measured with a 2V input step. The propagation delays are also measured with a 2V input step.
