(6) 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. Short circuit test is a momentary test. Output short circuit duration is
infinite for V
S
≤ 6V at room temperature and below. For V
S
> 6V, allowable short circuit duration is 1.5 ms.
(7) Slew rate is the slower of the rising and falling slew rates. Connected as a Voltage Follower.

(1) 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 ensured specification of parametric performance is indicated in the electrical
tables under conditions of internal self-heating where T
J
> T
A
.
(2) All limits are ensured by testing or statistical analysis.
(3) Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped
production material.
(4) Offset voltage temperature drift determined by dividing the change in V
OS
at temperature extremes into the total temperature change.
(5) Positive current corresponds to current flowing into the device.
