Current Limiting
The EL5492C has no internal current-limiting circuitry.
If the output is shorted, it is possible to exceed the Abso-
lute Maximum Rating for output current or power
dissipation, potentially resulting in the destruction of the
device.
Power Dissipation
With the high output drive capability of the EL5492C, it
is possible to exceed the 125°C Absolute Maximum
junction temperature under certain very high load cur-
rent conditions. Generally speaking when RL falls below
about 25
, it is important to calculate the maximum
junction temperature (TJMAX) for the application to
determine if power supply voltages, load conditions, or
package type need to be modified for the EL5492C to
remain in the safe operating area. These parameters are
calculated as follows:
where:
TMAX = Maximum ambient temperature
θJA = Thermal resistance of the package
n = Number of amplifiers in the package
PDMAX = Maximum power dissipation of each ampli-
fier in the package
PDMAX for each amplifier can be calculated as follows:
where:
VS = Supply voltage
ISMAX = Maximum supply current of 1A
VOUTMAX = Maximum output voltage (required)
RL = Load resistance
