not include heat removal or forcing air, or the simple fact that
the package will be attached to a circuit board, which can
also provide some form of heat removal. Larger temperature
and voltage ranges are possible with heat removal and
forcing air past the part.
Current Limit
The EL2360 has internal current limits that protect the circuit
in the event of an output being shorted to ground. This limit
is set at 100mA nominally and reduces with the junction
temperature. At T
65mA. If any one output is shorted to ground, the power
dissipation could be well over 1W, and much greater if all
outputs are shorted. Heat removal is required in order for the
EL2360 to survive an indefinite short.
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 de-
couple the EL2360 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 5: and
50:) can be placed in series with the output to eliminate
most peaking. The gain resistor (R
make up for any gain loss which may be created by this
additional resistor at the output. In many cases it is also
