Note 1:
All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 2:
These specifications are guaranteed by design and characterization; they are not production tested.
Note 3:
Absolute Maximum Ratingsindicate limits beyond which damage to the device may occur. Operating Ratingsindicate conditions for which the device is func-
tional, but do not guarantee specific performance limits. Electrical Characteristicsstate 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 4:
The maximum power dissipation must be derated at elevated temperatures and is dictated by T
JMAX
,
θ
JA
, and the ambient temperature T
A
. The maximum
allowable power dissipation is P
= (T
–T
)/
θ
or the number given inAbsolute Maximum Ratings, whichever is lower. For the LM4548, T
JMAX
= 150C. The
typical junction-to-ambient thermal resistance is 74C/W for package number VBH48A.
Note 5:
Human body model, 100 pF discharged through a 1.5 k
resistor.
Note 6:
Machine Model, 220 pF–240 pF discharged through all pins.
Note 7:
Typicals are measured at 25C and represent the parametric norm.
Note 8:
Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
