(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 TJ = TA. No guarantee of parametric performance is indicated in the electrical tables under
conditions of internal self heating where TJ > TA.
(2) Typical Values represent the most likely parametric norm.
(3) All limits are guaranteed by testing or statistical analysis.
(4) Offset voltage average drift determined by dividing the change in VOS at temperature extremes into the total temperature change.
(5) Positive current corresponds to current flowing into the device.
(6) Production Short Circuit test is a momentary test. See Note 7.
(7) Allowable Output Short Circuit duration is infinite for VS ≤ 6V at room temperature and below. For VS > 6V, allowable short circuit
duration is 1.5ms.
