(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 indication of parametric performance exists in the electrical tables under
conditions of internal self-heating where T_J > T_A.
(2) Limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlations using the
statistical quality control (SQC) method.
(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 specified on shipped
production material.
(4) Offset voltage average drift is determined by dividing the change in V_OS by temperature change.
(5) Parameter is specified by design and/or characterization and is not test in production.
(6) Positive current corresponds to current flowing into the device.
(7) The short circuit test is a momentary test, the short circuit duration is 1.5 ms.
