MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the
is
limited by the associated rise in junction temperature. For the
plastic packages, the maximum safe junction temperature is 145°C.
For the CERDIP and LCC packages, the maximum junction tem-
perature is 175°C. If these maximums are exceeded momentarily,
proper circuit operation is restored as soon as the die tempera-
ture is reduced. Leaving the device in the overheated condition
for an extended period can result in device burnout. To ensure
proper operation, it is important to observe the derating curves
in Figure 21 and Figure 24.
While the
is internally short-circuit protected, this may
not be sufficient to guarantee that the maximum junction tem-
perature is not exceeded under all conditions. An important
example is when the amplifier is driving a reverse-terminated
75 Ω cable and the cable’s far end is shorted to a power supply.
With power supplies of ±12 V (or less) at an ambient temperature
of +25°C or less, and the cable shorted to a supply rail, the
amplifier is not destroyed, even if this condition persists for
an extended period.
