(1) All limits are specified by testing or statistical analysis.
(2) 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. See APPLICATION INFORMATION for information on temperature de-rating of this
device.
(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 ensured on shipped
production material.
(4) 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.
