General Description
The EL2186C/EL2286C are single/dual current-feedback operational
amplifiers which achieve a -3dB bandwidth of 250MHz at a gain of +1
while consuming only 3mA of supply current per amplifier. They will
operate with dual supplies ranging from 1.5V to 6V, or from single
supplies ranging from +3V to +12V. The EL2186C/EL2286C also
include a disable/power-down feature which reduces current con-
sumption to 0mA while placing the amplifier output in a high
impedance state. In spite of its low supply current, the EL2286C can
output 55mA while swinging to 4V on 5V supplies. The EL2186C
can output 100mA with similar output swings. These attributes make
the EL2186C/EL2286C excellent choices for low power and/or low
voltage cable-driver, HDSL, or RGB applications.
For Single, Dual and Quad applications without disable, consider the
EL2180C (8-Pin Single), EL2280C (8-Pin Dual) or EL2480C (14-Pin
Quad). For lower power applications where speed is still a concern,
consider the EL2170C/El2176C family which also comes in similar
Single, Dual and Quad configurations. The EL2170C/EL2176C fam-
ily provides a -3dB bandwidth of 70MHz while consuming 1mA of
supply current per amplifier.

Applications Information
Product Description
The EL2186C/EL2286C are current-feedback opera-
tional amplifiers that offer a wide -3dB bandwidth of
250MHz, a low supply current of 3mA per amplifier and
the ability to disable to 0mA. Both products also feature
high output current drive. The EL2186C can output
100mA, while the EL2286C can output 55mA per
amplifier. The EL2186C/EL2286C work with supply
voltages ranging from a single 3V to 6V, and they are
also capable of swinging to within 1V of either supply
on the input and the output. Because of their current-
feedback topology, the EL2186C/EL2286C do not have
the normal gain- bandwidth product associated with
voltage-feedback operational amplifiers. This allows
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 EL2186C/EL2286C the ideal choice
for many low-power/high-bandwidth applications such
as portable computing, HDSL, and video processing.
For Single, Dual and Quad applications without disable,
consider the EL2180C (8-Pin Single), EL2280C (8-Pin
Dual) and EL2480C (14-Pin Quad). If lower power is
required, refer to the EL2170C/EL2176C family which
provides Singles, Duals, and Quads with 70MHz of
bandwidth while consuming 1mA of supply current per
amplifier.
Power Supply Bypassing and Printed Circuit
Board Layout
As with any high-frequency device, good printed circuit
board layout is necessary for optimum performance.
Ground plane construction is highly recommended.
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 4.7F tantalum capac-
itor in parallel with a 0.1F 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).
Ground plane construction should be used, but 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 their additional series inductance. Use of
sockets, particularly for the SO package should be
avoided if possible. Sockets add parasitic inductance and
capacitance which will result in some additional peak-
ing and overshoot.
Disable/Power-Down
The EL2186C/EL2286C amplifiers can be disabled,
placing their output in a high-impedance state. When
disabled, each amplifier's supply current is reduced to
0mA. Each EL2186C/EL2286C amplifier is disabled
when its ENABLE pin is floating or pulled up to within
0.5V of the positive supply. Similarly, each amplifier is
enabled by pulling its ENABLE pin at least 3V below
the positive supply. For 5V supplies, this means that an
EL2186C/EL2286C amplifier will be enabled when
ENABLE is at 2V or less, and disabled when ENABLE
is above 4.5V. Although the logic levels are not standard
TTL, this choice of logic voltages allows the
EL2186C/EL2286C to be enabled by tying ENABLE to
ground, even in +3V single-supply applications. The
ENABLE pin can be driven from CMOS outputs or
open-collector TTL.
When enabled, supply current does vary somewhat with
the voltage applied at ENABLE. For example, with the
supply voltages of the EL2186C at 5V, if ENABLE is
tied to -5V (rather than ground) the supply current will
increase about 15% to 3.45mA.
Capacitance at the Inverting Input
Any manufacturer's high-speed voltage- or current-feed-
back 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 capaci-
tance (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 further exacerbates the problem by further low-
ering the pole frequency.
The EL2186C/EL2286C have been specially designed
to reduce power dissipation in the feedback network by
using large 750
feedback and gain resistors. With the
high bandwidths of these amplifiers, these large resistor
values would normally cause stability problems when
combined with parasitic capacitance, but by internally
canceling the effects of a nominal amount of parasitic
capacitance, the EL2186C/EL2286C remain very stable.
For less experienced users, this feature makes the
EL2186C/EL2286C much more forgiving, and therefore
easier to use than other products not incorporating this
proprietary circuitry.
The experienced user with a large amount of PC board
layout experience may find in rare cases that the
EL2186C/EL2286C have less bandwidth than expected.
In this case, the inverting input may have less parasitic
capacitance than expected
by the internal compensation circuitry of the
EL2186C/EL2286C. The reduction of feedback resistor
values (or the addition of a very small amount of exter-
nal capacitance at the inverting input, e.g. 0.5pF) will
increase bandwidth as desired. Please see the curves for
Frequency Response for Various R
F
and R
G
, and Fre-
quency Response for Various C
IN-
.
Feedback Resistor Values
The EL2186C/EL2286C have been designed and speci-
fied at gains of +1 and +2 with R
F
= 750
. This value of
feedback resistor gives 250MHz of -3dB bandwidth at
A
V
= +1 with about 2.5dB of peaking, and 180MHz of -
3dB bandwidth at A
V
= +2 with about 0.1dB of peaking.
Since the EL2186C/EL2286C are current-feedback
amplifiers, it is also possible to change the value of R
F
to
get more bandwidth. As seen in the curve of Frequency
Response For Various R
F
and R
G
, bandwidth and peak-
ing can be easily modified by varying the value of the
feedback resistor.
Because the EL2186C/EL2286C are current-feedback
amplifiers, their gain-bandwidth product is not a con-
stant for different closed-loop gains. This feature
actually allows the EL2186C/EL2286C to maintain
about the same -3dB bandwidth, regardless of closed-
loop gain. However, as closed-loop 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 R
F
below the specified 750
and still retain stability, result-
ing in only a slight loss of bandwidth with increased
closed-loop gain.
Supply Voltage Range and Single-Supply
Operation
The EL2186C/EL2286C have been designed to operate
with supply voltages having a span of greater than 3V,
and less than 12V. In practical terms, this means that the
EL2186C/EL2286C will operate on dual supplies rang-
ing from 1.5V to 6V. With a single-supply, the
EL2176C will operate from +3V to +12V.
As supply voltages continue to decrease, it becomes nec-
essary to provide input and output voltage ranges that
can get as close as possible to the supply voltages. The
EL2186C/EL2286C have an input voltage range that
extends to within 1V of either supply. So, for example,
on a single +5V supply, the EL2186C/EL2286C have an
input range which spans from 1V to 4V. The output
range of the EL2186C/EL2286C is also quite large,
extending to within 1V of the supply rail. On a 5V sup-
ply, the output is therefore capable of swinging from -
4V to +4V. Single-supply output range is even larger
because of the increased negative swing due to the exter-
nal pull-down resistor to ground. On a single +5V
supply, output voltage range is about 0.3V to 4V.
Video Performance
For good video performance, an amplifier is required to
maintain the same output impedance and the same fre-
quency 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. Until the EL2186C/EL2286C, good Dif-
ferential 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 3mA supply current of
each EL2186C/EL2286C amplifier! Special circuitry
has been incorporated in the EL2186C/EL2286C to
reduce the variation of output impedance with current

output. This results in dG and dP specifications of 0.05%
and 0.05 while driving 150
at a gain of +2.
Video Performance has also been measured with a 500
load at a gain of +1. Under these conditions, the
EL2186C/EL2286C have dG and dP specifications of
0.01% and 0.01 respectively while driving 500
at A
V
= +1.
Output Drive Capability
In spite of its low 3mA of supply current, the EL2186C
is capable of providing a minimum of 80mA of output
current. Similarly, each amplifier of the EL2286C is
capable of providing a minimum of 50mA. These out-
put drive levels are unprecedented in amplifiers running
at these supply currents. With a minimum 80mA of
output drive, the EL2186C is capable of driving 50
loads to 4V, making it an excellent choice for driving
isolation transformers in telecommunications applica-
tions. Similarly, the 50mA minimum output drive of
each EL2286C amplifier allows swings of 2.5V into
50
loads.
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 resis-
tor will decouple the EL2186C/EL2286C 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 peak-
ing. The gain resistor (R
G
) can then be chosen to make
up for any gain loss which may be created by this addi-
tional 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 EL2186C/EL2286C have no internal current-limit-
ing circuitry. If any output is shorted, it is possible to
exceed the Absolute Maximum Ratings for output cur-
rent or power dissipation, potentially resulting in the
destruction of the device.

EL2186C/EL2286C, it is possible to exceed the 150C
Absolute Maximum junction temperature under certain
very high load current conditions. Generally speaking,
when R
L
falls below about 25
, it is important to calcu-
late 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
EL2186C/EL2286C to remain in the safe operating area.
