Note 1:
Any of the amplifier outputs can be shorted to ground indefinitely; however, more than one should not be simultaneously shorted as the maximum junction
temperature will be exceeded.
Note 2:
The maximum power dissipation for these devices must be derated at elevated temperatures and is dicated by T
JMAX
,
θ
JA
, and the ambient temperature,
T
A
. The maximum available power dissipation at any temperature is P
d
= (T
JMAX
− T
A
)/θ
JA
or the 25˚C P
DMAX
, whichever is less.
Note 3:
These specifications apply for V
S
=
±
15V and over the absolute maximum operating temperature range (T
L
≤
T
A
≤
T
H
) unless otherwise noted.
Note 4:
Refer to RETS 148X for LM148 military specifications.
