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 specification of parametric performance is indicated in the electrical tables under
conditions of internal self-heating where T
J
> T
A
. Absolute Maximum Ratings indicate junction temperature limits beyond which the
device may be permanently degraded, either mechanically or electrically.
Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlations using
statistical quality control (SQC) method.
Typical values represent the most likely parametric norm 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.
Offset voltage temperature drift is determined by dividing the change in V
OS
at the temperature extremes by the total temperature
change.
This parameter is ensured by design and/or characterization and is not tested in production.
Positive Bias Current corresponds to current flowing into the device.
