Current Limiting
The ISL28276 and ISL28476 have no internal current-
limiting circuitry. If the output is shorted, it is possible to
exceed the Absolute Maximum Rating for output current or
power dissipation, potentially resulting in the destruction of
the device.
Power Dissipation
It is possible to exceed the +150°C maximum junction
temperatures under certain load and power-supply
conditions. It is therefore important to calculate the
maximum junction temperature (T
JMAX
) for all applications
to determine if power supply voltages, load conditions, or
package type need to be modified to remain in the safe
operating area. These parameters are related as follows:
where:
P
DMAXTOTAL
is the sum of the maximum power
dissipation of each amplifier in the package (PD
MAX
)
PD
MAX
for each amplifier can be calculated as follows:
where:
T
