(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 specification of parametric performance is indicated in the electrical tables under
conditions of internal self-heating where T_J > T_A. See for information on temperature de-rating of this device." Min/Max ratings are based
on product characterization and simulation. Individual parameters are tested as noted.
(2) Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation using Statistical
Quality Control (SQC) methods.
(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) I_BI is referred to a differential output offset voltage by the following relationship: V_OD(offset) = I_BI*2R_F
(5) Short circuit current should be limited in duration to no more than 10 seconds. See Power Dissipation for more details.
