(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 guarantee of parametric performance is indicated in the electrical tables under
conditions of internal self heating where T
J
> T
A
.
(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 V
OS
at temperature extremes into the total temperature change.
(5) Positive current corresponds to current flowing into the device.
