(7) Drift determined by dividing the change in parameter at temperature extremes by the total temperature change.
(8) Negative input current implies current flowing out of the device.
(9) The maximum output current (I_OUT) is determined by device power dissipation limitations.

(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.
(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 numbers are the most likely parametric norm.
(4) Slew Rate is the average of the rising and falling edges.
