capable of driving 50
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 EL5292 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
G
) can then be chosen to
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
F
) to reduce the peaking.
Current Limiting
The EL5292 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 EL5292, it is
possible to exceed the 125°C Absolute Maximum junction
temperature under certain very high load current conditions.
Generally speaking when R
L
falls below about 25
, it is
important to calculate the maximum junction temperature
(T
JMAX
) for the application to determine if power supply
voltages, load conditions, or package type need to be
modified for the EL5292 to remain in the safe operating area.
These parameters are calculated as follows:
where:
T
MAX
= Maximum ambient temperature
θ
JA
= Thermal resistance of the package
n = Number of amplifiers in the package
PD
MAX
= Maximum power dissipation of each amplifier in
the package
PD
MAX
for each amplifier can be calculated as follows:
where:
V
S
= Supply voltage
I
SMAX
= Maximum supply current of 1A
V
OUTMAX
= Maximum output voltage (required)
