(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 TJ = TA. No specification of parametric performance is indicated in the electrical tables under conditions of internal self-heating where TJ > TA. See Thermal Information 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) Short circuit current should be limited in duration to no more than 10 seconds. See Power Dissipation for more details.
(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) Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation using Statistical Quality Control (SQC) methods.
(5) Negative input current implies current flowing out of the device.
(6) IBI is referred to a differential output offset voltage by the following relationship: VOD(OFFSET) = IBI*2RF.
(7) VEN threshold is typically +/-0.3V centered around (V+ + V-) / 2 relative to ground.
(8) For test schematic, refer to Figure 34.
