Electrical Characteristics V
DD
= 5.0V
(Notes 1, 2) (Continued)
Note 2:
Absolute Maximum Ratings
indicate limits beyond which damage to the device may occur.
Operating Ratings
indicate conditions for which the device is
functional, but do not guarantee specific performance limits.
Electrical Characteristics
state DC andAC electrical specifications under particular test conditions which
guarantee 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
JMAX
,
θ
JA
, and the ambient temperature, T
A
. The maximum
allowable power dissipation is P
DMAX
= (T
JMAX
T
A
) /
θ
JA
or the given in Absolute Maximum Ratings, whichever is lower. For the LM4960 typical application (shown
in
Figure 1
) with V
DD
= 12V, R
L
= 4
stereo operation the total power dissipation is 3.65W.
θ
JA
= 35C/W.
Note 4:
Human body model, 100pF discharged through a 1.5k
resistor.
Note 5:
Machine Model, 220pF–240pF 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:
Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis.
Note 9:
Shutdown current is measured in a normal room environment. The Shutdown pin should be driven as close as possible to V
DD
for minimum shutdown
current.
