(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 ensured specification of parametric performance is indicated in the electrical
tables under conditions of internal self-heating where T
J
> T
A
(2) For annotation brevity, “HP”=High Power, “MP”=Medium Power, “LP” =Low Power, “DIS”=Disabled or shut down, “SE”=Single Ended
Mode, “DM”=Differential Mode. See Table 1 in Applications section for power setting details. It is also assumed R

(3) Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlations using the
Statistical Quality Control (SQC) method.
(4) 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.
(5) Drift Determined by dividing the change in parameter at temperature extremes by the total temperature change. Value is the worst case
of Ta
