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, 1.5 kΩ in series with 100 pF. Machine model, 200Ω 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:
Connected as voltage follower with 1V step input. Number specified is the slower of the positive and negative slew rate.
