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 5
Ω
and 50
Ω
) 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 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
when R
L
falls below about 25
Ω
, it is important to calculate
the maximum junction temperature (TJ
MAX
) for the
application to determine if power supply voltages, load
conditions, or package type need to be modified for the
EL5160, EL5161, EL5260, EL5261, and EL5360 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 0.75mA
V
OUTMAX
= Maximum output voltage (required)
R
L
= Load resistance
