(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.
(2) The maximum output current (IOUT) is determined by device power dissipation limitations.
(3) The maximum power dissipation is a function of TJ(MAX), θJA and TA. The maximum allowable power dissipation at any ambient temperature is P D= (TJ(MAX) — TA)/ θJA. All numbers apply for package soldered directly into a 2 layer PC board with zero air flow.
(4) Slew Rate is the average of the rising and falling edges.
(5) Typical numbers are the most likely parametric norm.
(6) Limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlation using Statistical Quality Control (SQC) methods.
(7) Negative input current implies current flowing out of the device.
(8) Drift determined by dividing the change in parameter at temperature extremes by the total temperature change.
