Single 300MHz Current Feedback
Amplifier with Enable
EL5193, EL5193A
May 16, 2007
FN7182.4
Features
• 300MHz -3dB bandwidth
The EL5193 and EL5193A are current feedback amplifiers
with a bandwidth of 300MHz. This makes these amplifiers
ideal for todays high speed video and monitor applications.
With a supply current of just 4mA and the ability to run from
a single supply voltage from 5V to 10V, these amplifiers are
also ideal for hand held, portable or battery-powered
equipment.
The EL5193A also incorporates an enable and disable
function to reduce the supply current to 100µA typical per
amplifier. Allowing the CE pin to float or applying a low logic
level will enable the amplifier.
The EL5193 is offered in the 5 Ld SOT-23 package and the
EL5193A is available in the 6 Ld SOT-23 as well as the
industry-standard 8 Ld SOIC packages. Both operate over
the industrial temperature range of -40°C to +85°C.
• 4mA supply current
• Single and dual supply operation, from 5V to 10V supply
span
• Fast enable/disable (EL5193A only)
• Available in SOT-23 packages
• Dual (EL5293) and triple (EL5393) available
• High speed, 1GHz product available (EL5193)
• High speed, 6mA, 600MHz product available (EL5192,
EL5292, and EL5392)
• Pb-free plus anneal available (RoHS compliant)
Applications
• Battery powered equipment
• Hand held, portable devices
• Video amplifiers
• Cable drivers
• RGB amplifiers
• Test equipment

Applications Information
Product Description
The EL5193 is a current-feedback operational amplifier that
offers a wide -3dB bandwidth of 300MHz and a low supply
current of 4mA per amplifier. The EL5193 works with supply
voltages ranging from a single 5V to 10V and they are also
capable of swinging to within 1V of either supply on the
output. Because of their current-feedback topology, the
EL5193 does not have the normal gain-bandwidth product
associated with voltage-feedback operational amplifiers.
Instead, its -3dB bandwidth to remain relatively constant as
closed-loop gain is increased. This combination of high
bandwidth and low power, together with aggressive pricing
make the EL5193 the ideal choice for many low-power/highbandwidth applications such as portable, handheld, or
battery-powered equipment.
For varying bandwidth needs, consider the EL5191 with 1GHz
on a 9mA supply current or the EL5192 with 600MHz on a 6mA
supply current. Versions include single, dual, and triple amp
packages with 5 Ld SOT-23, 16 Ld QSOP, and 8 Ld or 16 Ld
SOIC outlines.

Power Supply Bypassing and Printed Circuit
Board Layout
As with any high frequency device, good printed circuit
board layout is necessary for optimum performance. Low
impedance ground plane construction is essential. Surface
mount components are recommended, but if leaded
components are used, lead lengths should be as short as
possible. The power supply pins must be well bypassed to
reduce the risk of oscillation. The combination of a 4.7µF
tantalum capacitor in parallel with a 0.01µF capacitor has
been shown to work well when placed at each supply pin.
For good AC performance, parasitic capacitance should be
kept to a minimum, especially at the inverting input. (See the
Capacitance at the Inverting Input section) Even when
ground plane construction is used, it should be removed
from the area near the inverting input to minimize any stray
capacitance at that node. Carbon or Metal-Film resistors are
acceptable with the Metal-Film resistors giving slightly less
peaking and bandwidth because of additional series
inductance. Use of sockets, particularly for the SOIC
package, should be avoided if possible. Sockets add

parasitic inductance and capacitance which will result in
additional peaking and overshoot.
resulting in only a slight loss of bandwidth with increased
closed-loop gain.
Disable/Power-Down
Supply Voltage Range and Single-Supply
Operation
The EL5193A amplifier can be disabled placing its output in
a high impedance state. When disabled, the amplifier supply
current is reduced to < 150µA. The EL5193A is disabled
when its CE pin is pulled up to within 1V of the positive
supply. Similarly, the amplifier is enabled by floating or
pulling its CE pin to at least 3V below the positive supply. For
±5V supply, this means that an EL5193A amplifier will be
enabled when CE is 2V or less, and disabled when CE is
above 4V. Although the logic levels are not standard TTL,
this choice of logic voltages allows the EL5193A to be
enabled by tying CE to ground, even in 5V single supply
applications. The CE pin can be driven from CMOS outputs.
Capacitance at the Inverting Input
Any manufacturer’s high-speed voltage- or current-feedback
amplifier can be affected by stray capacitance at the
inverting input. For inverting gains, this parasitic capacitance
has little effect because the inverting input is a virtual
ground, but for non-inverting gains, this capacitance (in
conjunction with the feedback and gain resistors) creates a
pole in the feedback path of the amplifier. This pole, if low
enough in frequency, has the same destabilizing effect as a
zero in the forward open-loop response. The use of largevalue feedback and gain resistors exacerbates the problem
by further lowering the pole frequency (increasing the
possibility of oscillation).
The EL5193 has been optimized with a 475Ω feedback
resistor. With the high bandwidth of these amplifiers, these
resistor values might cause stability problems when
combined with parasitic capacitance, thus ground plane is
not recommended around the inverting input pin of the
amplifier.
Feedback Resistor Values
The EL5193 has been designed and specified at a gain of +2
with RF approximately 500Ω. This value of feedback resistor
gives 200MHz of -3dB bandwidth at AV=2 with 2dB of
peaking. With AV=-2, an RF of approximately 500Ω gives
175MHz of bandwidth with 0.2dB of peaking. Since the
EL5193 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 EL5193 is a current-feedback amplifier, its
gain-bandwidth product is not a constant for different closedloop gains. This feature actually allows the EL5193 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 475Ω and still retain stability,
15
The EL5193 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 the EL5193 will operate
on dual supplies ranging from ±2.5V to ±5V. With singlesupply, the EL5193 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
EL5193 has an input range which extends to within 2V of
either supply. So, for example, on +5V supplies, the EL5193
has an input range which spans ±3V. The output range of the
EL5193 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 150Ω, 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 4mA
supply current of each EL5193 amplifier. Special circuitry
has been incorporated in the EL5193 to reduce the variation
of output impedance with current output. This results in dG
and dP specifications of 0.03% 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 EL5193 has
dG and dP specifications of 0.03% and 0.04°.
Output Drive Capability
In spite of its low 4mA of supply current, the EL5193 is
capable of providing a minimum of ±95mA of output current.
With a minimum of ±95mA of output drive, the EL5193 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 EL5193 from the cable and allow extensive
capacitive drive. However, other applications may have high
capacitive loads without a back-termination resistor. In these
FN7182.4
May 16, 2007
EL5193, EL5193A
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 (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 EL5193 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 EL5193, 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 25Ω, 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 EL5193 to remain in the safe operating area.
These parameters are calculated as follows:
T JMAX = T MAX + ( θ JA × n × PD MAX )
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
PDMAX for each amplifier can be calculated as follows:
V OUTMAX
PD MAX = ( 2 × V S × I SMAX ) + ( V S - V OUTMAX ) × ---------------------------R
L
where:
VS = Supply voltage
ISMAX = Maximum supply current of 1A
VOUTMAX = Maximum output voltage (required)
RL = Load resistance
