Driving Cables and Capacitive Loads
When used as a cable driver, double termination is always
recommended for reflection-free performance. For those
applications, the back-termination series resistor will
decouple the EL5160, EL5161, EL5260, EL5261, and
EL5360 from the cable and allow extensive capacitive drive.
However, other applications may have high capacitive loads
without a back-termination resistor. In these applications, a
small series resistor (usually between 5Ω and 50Ω) can be
placed in series with the output to eliminate most peaking.
The gain resistor (R
any gain loss which may be created by this additional
resistor at the output. In many cases it is also possible to
simply increase the value of the feedback resistor (R
reduce the peaking.
Current Limiting
The EL5160, EL5161, EL5260, EL5261, and EL5360 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
With the high output drive capability of the EL5160, EL5161,
EL5260, EL5261, and EL5360, it is possible to exceed the
+125°C Absolute Maximum junction temperature under
certain very high load current conditions. Generally speaking
