200MHz Low-Power Current Feedback
Amplifiers
The EL5160, EL5161, EL5260, EL5261, and EL5360 are
current feedback amplifiers with a bandwidth of 200MHz and
operate from just 0.75mA supply current. This makes these
amplifiers ideal for today’s high speed video and monitor
applications.
Features
• 200MHz -3dB bandwidth
• 0.75mA supply current
• 1700V/µs slew rate
• Single and dual supply operation, from 5V to 10V supply
span
With the ability to run from a single supply voltage from 5V to
10V, these amplifiers are ideal for handheld, portable, or
battery-powered equipment.
• Fast enable/disable (EL5160, EL5260 & EL5360 only)
• Available in SOT-23 packages
• Pb-Free plus anneal available (RoHS compliant)
The EL5160 also incorporates an enable and disable
function to reduce the supply current to 14µA typical per
amplifier. Allowing the CE pin to float or applying a low logic
level will enable the amplifier.
Applications
• Battery-powered equipment
• Handheld, portable devices
• Video amplifiers
The EL5160 is available in the 6-pin SOT-23 and 8-pin SO
packages, the EL5161 in 5-pin SOT-23 and SC-70
packages, the EL5260 in the 10-pin MSOP package, the
EL5261 in 8-pin SO and MSOP packages, the EL5360 in
16-pin SO and QSOP packages. All operate over the
industrial temperature range of -40°C to +85°C.
• Cable drivers
• RGB amplifiers
• Test equipment
• Instrumentation
• Current-to-voltage converters

Power Supply Bypassing and Printed Circuit
Board Layout
Applications Information
Product Description
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.
The EL5160, EL5161, EL5260, EL5261, and EL5360 are low
power, current-feedback operational amplifiers that offer a
wide -3dB bandwidth of 200MHz and a low supply current of
0.75mA per amplifier. The EL5160, EL5161, EL5260,
EL5261, and EL5360 work 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 EL5160, EL5161, EL5260,
EL5261, and EL5360 do not have the normal gain-
bandwidth product associated with voltage-feedback
operational amplifiers. Instead, their -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 EL5160, EL5161, EL5260,
EL5261, and EL5360 ideal choices for many low-
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 SO package,
should be avoided if possible. Sockets add parasitic
power/high-bandwidth applications such as portable,
handheld, or battery-powered equipment.

peaking and overshoot.

retain stability, resulting in only a slight loss of bandwidth
The EL5160 amplifier can be disabled placing its output in a
high impedance state. When disabled, the amplifier supply
current is reduced to < 15µA. The EL5160 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 EL5160 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 EL5160 to be enabled by tying CE
to ground, even in 5V single supply applications. The CE pin
can be driven from CMOS outputs.
with increased closed-loop gain.
Supply Voltage Range and Single-Supply
Operation
The EL5160, EL5161, EL5260, EL5261, and EL5360 have
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 EL5160,
EL5161, EL5260, EL5261, and EL5360 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
EL5160, EL5161, EL5260, EL5261, and EL5360 have an
input range which extends to within 2V of either supply. So,
for example, on +5V supplies, the EL5160, EL5161, EL5260,
EL5261, and EL5360 have an input range which spans ±3V.
The output range of the EL5160, EL5161, EL5260, EL5261,
and EL5360 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.
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 large-
value feedback and gain resistors exacerbates the problem
by further lowering the pole frequency (increasing the
possibility of oscillation.)
Video Performance
The EL5160, EL5161, EL5260, EL5261, and EL5360 have
been optimized with a TBDΩ 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.
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 1mA
supply current of each EL5160, EL5161, EL5260, EL5261,
and EL5360 amplifier. Special circuitry has been
Feedback Resistor Values

EL5160, EL5161, EL5260, EL5261, and EL5360 are current-

R to get more bandwidth. As seen in the curve of

EL5360 are current-feedback amplifiers, their gain-
In spite of their low 1mA of supply current, the EL5160,
EL5161, EL5260, EL5261, and EL5360 are capable of
providing a minimum of ±50mA of output current. With a
minimum of ±50mA of output drive, the EL5160 is capable of
driving 50Ω loads to both rails, making it an excellent choice
for driving isolation transformers in telecommunications
applications.
bandwidth product is not a constant for different closed-loop
gains. This feature actually allows the EL5160, EL5161,
EL5260, EL5261, and EL5360 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

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 5Ω and 50Ω) can be
placed in series with the output to eliminate most peaking.
