General Description
The EL2386C is a triple current-feedback operational amplifier
which achieves a
while consuming only 3 mA of supply current per amplifier. It
will operate with dual supplies ranging from
from single supplies ranging from
also includes a disable/power-down feature which reduces current consumption to 0 mA while placing the amplifier output in
a high impedance state. In spite of its low supply current, the
EL2386C can output 55 mA while swinging to
supplies. These attributes make the EL2386C an excellent
choice for low power and/or low voltage cable-driver, HDSL, or
RGB applications.
For Single and Dual applications, consider the EL2186C/
EL2286C. For Single, Dual and Quad applications without disable, consider the EL2180C, EL2280C, or EL2480C, all in industry standard pin outs. The EL2180C also is available in the tiny
SOT-23 package, which is 28% the size of an SO8 package. 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
family provides a
ing 1 mA of supply current per amplifier.

Applications Information
Product Description
The EL2386C is a current-feedback operational
amplifier that offers a wide
250 MHz, a low supply current of 3 mA per amplifier and the ability to power down to 0 mA. It
also features high output current drive. The
EL2386C can output 55 mA per amplifier. The
EL2386C works with supply voltages ranging
from a single 3V to
swinging to within 1V of either supply on the
input and the output. Because of its current-feedback topology, the EL2386C does not have the
normal gain-bandwidth product associated with
voltage-feedback operational amplifiers. This allows its
constant as closed-loop gain is increased. This
combination of high bandwidth and low power,
together with aggressive pricing make the
EL2386C the ideal choice for many low-power/
high-bandwidth applications such as portable
computing, HDSL, and video processing.
For Single and Dual applications, consider the
EL2186C/EL2286C. For Single, Dual and Quad
applications without disable, consider the
EL2180C, EL2280C, or EL2480C, all in industry
standard pin outs. The EL2180C also is available
in the tiny SOT-23 package, which is 28% the
size of an SO8 package. 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
with 70 MHz of bandwidth while consuming
1 mA 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 4.7 mF tantalum capacitor in
parallel with a 0.1 mF capacitor has been shown
to work well when placed at each supply pin. For
single supply operation, where pin 3 (V

) is con-
S-
EL2386C
nected to the ground plane, a single 4.7 mF tantalum capacitor in parallel with a 0.1 mF ceramic
capacitor across pins 14 and 3 will suffice.
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 peaking and
overshoot.
Disable/Power-Down
The EL2386C amplifier can be disabled, placing
its output in a high-impedance state. When disabled, the supply current is reduced to 0 mA. The
EL2386C is disabled when its ENABLE
floating or pulled up to within 0.5V of the positive supply. Similarly, the amplifier is enabled by
pulling its ENABLE
positive supply. For
that an EL2386C amplifier will be enabled when

voltages allows the EL2386C to be enabled by tying ENABLE

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 further exacerbates the
problem by further lowering the pole frequency.
The experienced user with a large amount of PC
board layout experience may find in rare cases
that the EL2386C has less bandwidth than expected. In this case, the inverting input may have
less parasitic capacitance than expected. The reduction of feedback resistor values (or the addition of a very small amount of external capacitance at the inverting input, e. g. 0.5 pF) will
increase bandwidth as desired. Please see the
curves for Frequency Response for Various R
and RG, and Frequency Response for Various
C

more bandwidth. As seen in the curve of Frequency Response For Various R
and RG, band-

width and peaking can be easily modified by
varying the value of the feedback resistor.
Because the EL2386C is a current-feedback amplifier, its gain-bandwidth product is not a constant for different closed-loop gains. This feature
actually allows the EL2386C to maintain about
the same
b
3 dB bandwidth, regardless of closed-
loop gain. However, as closed-loop gain is in-
creased, 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
below the spec-
F
ified 750X and still retain stability, resulting in
only a slight loss of bandwidth with increased
closed-loop gain.
Supply Voltage Range and SingleSupply Operation
The EL2386C has 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 EL2386C will operate on dual supplies
ranging from
g
1.5V tog6V. With a single-sup-
ply, the EL2386C will operate from
a
12V.
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 EL2386C has an input
voltage range that extends to within 1V of either
supply. So, for example, on a single
the EL2386C has an input range which spans
F
from 1V to 4V. The output range of the EL2386C
is also quite large, extending to within 1V of the
supply rail. On a
therefore capable of swinging from
g
5V supply, the output is
b
Single-supply output range is even larger because
of the increased negative swing due to the external pull-down resistor to ground. On a single
a
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 frequency response as DC levels are
changed at the output. This is especially difficult
when driving a standard video load of 150X, because of the change in output current with DC
level. Until the EL2386C, 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 3 mA
supply current of each EL2386C amplifier! Spe-

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 EL2386C
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 5X and 50X) can be placed
in series with the output to eliminate most peaking. The gain resistor (R
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

Current Limiting
The EL2386C has no internal current-limiting
circuitry. If an output is shorted indefinitely, the
power dissipation could easily increase such that
the part will be destroyed. Maximum reliability
is maintained if the output current never exceeds
g
60 mA. A heat sink may be required to keep
the junction temperature below absolute maximum when an output is shorted indefinitely.
Multiplexing with the EL2386C
The ENABLE pins on the EL2386C allow for
multiplexing applications. Figure 1 shows an
EL2386C with all 3 outputs tied together, driving
a back terminated 75X video load. Three sine
waves of varying amplitudes and frequencies are
applied to the three inputs, whilea1of3decoder
