EL5196C, EL5196AC
Single 400MHz Fixed Gain Amplifier with Enable
Current Limiting
The EL5196C 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 EL5196C, it
is possible to exceed the 125°C Absolute Maximum
junction temperature under certain very high load cur-
rent conditions. Generally speaking when R
about 25Ω, it is important to calculate the maximum
junction temperature (T
determine if power supply voltages, load conditions, or
package type need to be modified for the EL5196C to
remain in the safe operating area. These parameters are
calculated as follows:
