(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) Typical values represent the most likely parametric norm 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.

(3) All limits are specified by testing, design, or statistical analysis.

(4) Offset voltage temperature drift is determined by dividing the change in V_OS at the temperature extremes by the total temperature change.

(5) The number specified is the average of rising and falling slew rates and measured at 90% to 10%.

(6) This parameter is specified by design and/or characterization and is not tested in production.

(7) Positive Bias Current corresponds to current flowing into the device.
