Note 1:
For supply voltages less than
±
15V, the absolute maximum input voltage is equal to the supply voltage.
Note 2:
The maximum power dissipation for these devices must be derated at elevated temperatures and is dictated by T
,
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 25C P
dMAX
, whichever is less.
Note 3:
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 4:
These specifications apply over the absolute maximum operating temperature range unless otherwise noted.
Note 5:
Refer to RETS146X for LM146J military specifications.
