500MHz Low Power Current Feedback
Amplifier
The EL5462 is a current feedback amplifier with a bandwidth
of 500MHz which makes this amplifier ideal for today’s high
speed video and monitor applications.
With a supply current of just 1.5mA per amplifier and the
ability to run from a single supply voltage from 5V to 12V, the
EL5462 is also ideal for handheld, portable or battery-
powered equipment.
The EL5462 is available in a 14-pin SO package and
operates over the industrial temperature range of -40°C to
+85°C.

EL5462
Feedback Resistor Values
The EL5462 has been designed and specified at a gain of +1
with RF approximately 606. This value of feedback resistor
gives 500MHz of -3dB bandwidth at AV = 1 with 0.5dB of
peaking. With AV = -2, an RF of approximately 600gives
300MHz of bandwidth with 1dB of peaking. Since the
EL5462 is a current-feedback amplifier, it is also possible to
change the value of RF to get more bandwidth. As seen in
the curve of Frequency Response for Various RF and RG,
bandwidth and peaking can be easily modified by varying the
value of the feedback resistor.
Because the EL5462 is a current-feedback amplifier, its
gain-bandwidth product is not a constant for different closed-
loop gains. This feature actually allows the EL5462 to
maintain about the same -3dB bandwidth. As gain is
increased, bandwidth decreases slightly while stability
increases. Since the loop stability is improving with higher
closed-loop gains, it becomes possible to reduce the value
of RF below the specified TBDand still retain stability,
resulting in only a slight loss of bandwidth with increased
closed-loop gain.
Supply Voltage Range and Single-Supply
Operation
The EL5462 has been designed to operate with supply
voltages having a span of greater than 5V and less than 10V.
In practical terms, this means that they will operate on dual
supplies ranging from ±2.5V to ±5V. With single-supply, the
EL5462 will operate from 5V to 10V.
As supply voltages continue to decrease, it becomes
necessary to provide input and output voltage ranges that
can get as close as possible to the supply voltages. The
EL5462 has an input range which extends to within 2V of
either supply. So, for example, on +5V supplies, the EL5462
has an input range which spans ±3V. The output range of the
EL5462 is also quite large, extending to within 1V of the
supply rail. On a ±5V supply, the output is therefore capable
of swinging from -4V to +4V. Single-supply output range is
larger because of the increased negative swing due to the
external pull-down resistor to ground.
Video Performance
For good video performance, an amplifier is required to
maintain the same output impedance and the same
frequency response as DC levels are changed at the output.
This is especially difficult when driving a standard video load
of 150, because of the change in output current with DC
level. Previously, good differential gain could only be
achieved by running high idle currents through the output
transistors (to reduce variations in output impedance.)
These currents were typically comparable to the entire 1mA
supply current of the EL5462 amplifier. Special circuitry has
been incorporated in the EL5462 to reduce the variation of
output impedance with current output. This results in dG and
dP specifications of 0.1% and 0.1°,wwwhwile.DdartiaviSnhge1e5t40U.caotma
gain of 2.
Video performance has also been measured with a 500
load at a gain of +1. Under these conditions, the EL5462 has
dG and dP specifications of 0.1% and 0.1°.
Output Drive Capability
In spite of its low 1.5mA of supply current, the EL5462 is
capable of providing a minimum of ±50mA of output current.
With a minimum of ±50mA of output drive, the EL5462 is
capable of driving 50loads 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 EL5462 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 5and
50) can be placed in series with the output to eliminate
most peaking. The gain resistor (RG) 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 (RF) to reduce the peaking.
Current Limiting
The EL5462 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 EL5462, it is
possible to exceed the 125°C Absolute Maximum junction
temperature under certain very high load current conditions.
Generally speaking when RL falls below about 25, it is
important to calculate the maximum junction temperature
(TJMAX) for the application to determine if power supply
voltages, load conditions, or package type need to be
modified for the EL5462 to remain in the safe operating area.
These parameters are calculated as follows:
TJMAX = TMAX + JA × n × PDMAX)
where:
• TMAX = Maximum ambient temperature
θJA = Thermal resistance of the package
• n = Number of amplifiers in the package
• PDMAX = Maximum power dissipation of each amplifier in
the package
