(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
. Parametric performance is indicated in the electrical tables under conditions of
internal self-heating where T
J
> T
A
.
(2) All limits are specified by testing or statistical analysis.
(3) Typical Values represent the most likely parametric norm.
(4) Slew rate is the average of the rising and falling slew rates
(5) Positive current corresponds to current flowing into the device.
(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.
