Note 1:
All voltages are measured with respect to the ground pins, unless otherwise specified.
Note 2:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is func-
tional, but do not guarantee specific performance limits. Electrical Characteristics state DC andAC electrical specifications under particular test conditions which guar-
antee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit is
given, however, the typical value is a good indication of device performance.
Note 3:
The maximum power dissipation must be derated at elevated temperatures and is dictated by T
,
θ
, and the ambient temperature T
. The maximum
allowable power dissipation is P
= (T
T
)/
θ
or the number given in the Absolute Maximum Ratings, whichever is lower. For the LM4860, T
JMAX
=
+150C, and the typical junction-to-ambient thermal resistance, when board mounted, is 100C/W.
Note 4:
Human body model, 100 pF discharged through a 1.5 k
resistor.
Note 5:
Machine Model, 200 pF–240 pF discharged through all pins.
Note 6:
Typicals are measured at 25C and represent the parametric norm.
Note 7:
Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 8:
The quiescent power supply current depends on the offset voltage when a practical load is connected to the amplifier.
Note 9:
Shutdown current has a wide distribution. For Power Management sensitive designs, contact your local National Semiconductor Sales Office.
