These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Refer to RETS 148X for LM148 military specifications.
(2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
(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.
(4) The maximum power dissipation for these devices must be derated at elevated temperatures and is dictated by T
JMAX
, θ
JA
, and the
ambient temperature, T
A
. The maximum available power dissipation at any temperature is P
