Note 2: 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. 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. www.national.com 4 |
