Electrical Characteristics
(Note 2)
(Continued)
Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications, see the Electrical Characteristics tables.
Note 2:
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 guarantee of parametric performance is indicated in the electrical tables under conditions of internal self-heating where T
J
>
T
A
.
Note 3:
The maximum output current (I
OUT
) is determined by device power dissipation limitations or value specified, whichever is lower.
Note 4:
Human body model: 1.5kΩ in series with 100pF. Machine model: 0Ω in series with 200pF.
Note 5:
Slew Rate is the average of the rising and falling rates.
Note 6:
Typical values represent the most likely parametric norm. Bold numbers refer to over temperature limits.
Note 7:
Positive current corresponds to current flowing in the device.
Note 8:
Drift determined by dividing the change in parameter distribution average at temperature extremes by the total temperature change.
