variation of output impedance with current output. This
results in dG and dP specifications of 0.015% and 0.04°,
while driving 150Ω at a gain of 2.
Video performance has also been measured with a 500Ω
load at a gain of +1. Under these conditions, the EL5392A
has dG and dP specifications of 0.03% and 0.05°,
respectively.
Output Drive Capability
In spite of its low 6mA of supply current, the EL5392A is
capable of providing a minimum of ±95mA of output current.
With a minimum of ±95mA of output drive, the EL5392A is
capable of driving 50Ω loads to both rails, making it an
excellent choice for driving isolation transformers in
telecommunications applications.
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 EL5392A 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
make up for 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
Current Limiting
The EL5392A has 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 EL5392A, it is
possible to exceed the 125°C Absolute Maximum junction
temperature under certain very high load current conditions.
