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 TJMAX, θJA, and the
ambient temperature, TA. The maximum available power dissipation at any temperature is Pd = (TJMAX − TA)/θJA or the 25°C PDMAX
,
whichever is less.
(5) Human body model, 1.5 kΩ in series with 100 pF.
Electrical Characteristics
These specifications apply for VS = ±15V and over the absolute maximum operating temperature range (TL ≤ TA ≤ TH) unless
otherwise noted.
