5V Electrical Characteristics (continued)
Unless otherwise specified, all limits guaranteed for at TJ = 25°C, V+ = 5V, V− = 0V, VCM = VO = V+/2, and Rf = 2kΩ, and RL =
1kΩ to V+/2. Boldface limits apply at the temperature extremes.

(7) Short circuit test is a momentary test.
(8) Output short circuit duration is infinite for VS < 6V at room temperature and below. For VS > 6V, allowable short circuit duration is 1.5ms.

(1) All limits are guaranteed by testing or statistical analysis.
(2) Typical values represent the most likely parametric norm.
(3) Slew rate is the average of the rising and falling slew rates.
(4) Positive current corresponds to current flowing into the device.
(5) Offset voltage average drift determined by dividing the change in VOS at temperature extremes into the total temperature change.
