600MHz Current Feedback Amplifiers with
Enable
The EL5164, EL5165, and EL5364 are current feedback
amplifiers with a very high bandwidth of 600MHz. This
makes these amplifiers ideal for today’s high speed video
and monitor applications.
With a supply current of just 5mA and the ability to run from
a single supply voltage from 5V to 12V, the amplifiers are
also ideal for hand held, portable or battery-powered
equipment.
The EL5164 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 EL5165 is offered in the 5 Ld SOT-23 and 5 Ld SC-70
packages, EL5164 is available in the 6 Ld SOT-23 and the
industry-standard 8 Ld SOIC packages, and the EL5364 in a
16 Ld SOIC and 16 Ld QSOP packages. All operate over the
industrial temperature range of -40°C to +85°C.

Product Description
The EL5164, EL5165, and EL5364 are current-feedback
operational amplifiers that offers a wide -3dB bandwidth of
600MHz and a low supply current of 5mA per amplifier. The
EL5164, EL5165, and EL5364 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 EL5164, EL5165, and
EL5364 do 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 EL5164, EL5165, and EL5364 ideal choices for
many low-power/high-bandwidth applications such as
portable, handheld, or battery-powered equipment.
For varying bandwidth needs, consider the EL5166 and
EL5167 with 1GHz on a 8.5mA supply current or the EL5162
and EL5163 with 300MHz on a 1.5mA supply current.
Versions include single, dual, and triple amp packages with
9
5 Ld SOT-23, 16 Ld QSOP, and 8 Ld SOIC 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” on page 10). 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
inductance and capacitance which will result in additional
peaking and overshoot.
Disable/Power-Down
The EL5164 amplifier can be disabled placing its output in a
high impedance state. When disabled, the amplifier supply
current is reduced to <150µA. The EL5164 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 EL5164 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 EL5164 to be enabled by tying CE
to ground, even in 5V single supply applications. The CE pin
can be driven from CMOS outputs.
When the amplifier is disabled, if the positive input is driven
beyond ±2V with respect to the negative input, the device
can become active and output the signal. An input diode
clamp network D1 and D2, as shown in Figure 23, can be
used to keep the device disabled while a large input signal is
present.

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 EL5164, EL5165, and EL5364 have been optimized
with a 510Ω 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.
10
The EL5164, EL5165, and EL5364 have been designed and
specified at a gain of +2 with RF approximately 412Ω. This
value of feedback resistor gives 300MHz of -3dB bandwidth
at AV = 2 with 2dB of peaking. With AV = -2, an RF of 300Ω
gives 275MHz of bandwidth with 1dB of peaking. Since the
EL5164, EL5165, and EL5364 are current-feedback
amplifiers, 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 EL5164, EL5165, and EL5364 are
current-feedback amplifiers, their gain-bandwidth product is
not a constant for different closed-loop gains. This feature
actually allows the EL5164, EL5165, and EL5364 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 160Ω and still retain stability,
resulting in only a slight loss of bandwidth with increased
closed-loop gain.
Supply Voltage Range and Single-Supply
Operation
RF
D1
Feedback Resistor Values
The EL5164, EL5165, and EL5364 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 EL5164, EL5165, and EL5364 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
EL5164, EL5165, and EL5364 have an input range which
extends to within 2V of either supply. So, for example, on
±5V supplies, the EL5164, EL5165, and EL5364 have an
input range which spans ±3V. The output range of the
EL5164, EL5165, and EL5364 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 5.5mA supply current of
FN7389.8
October 29, 2007
EL5164, EL5165, EL5364
each EL5164, EL5165, and EL5364 amplifiers. Special
circuitry has been incorporated in the EL5164, EL5165, and
EL5364 to reduce the variation of output impedance with
current output. This results in dG and dP specifications of
0.01% and 0.01°, 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 EL5164, EL5165,
and EL5364 have dG and dP specifications of 0.01% and
0.01°, respectively.
Output Drive Capability
In spite of their low 5.5mA of supply current, the EL5164,
EL5165, and EL5364 are capable of providing a minimum of
±75mA of output current. With a minimum of ±75mA of output
drive, the EL5164, EL5165, and EL5364 are 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
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 in Equation 2:
V OUTMAX
PD MAX = ( 2 × V S × I SMAX ) + ( V S – V OUTMAX ) × ---------------------------RL
(EQ. 2)
where:
• VS = Supply voltage
• ISMAX = Maximum supply current of 1A
• VOUTMAX = Maximum output voltage (required)
• RL = Load resistance
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 EL5164, EL5165, and EL5364 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. 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.

Power Dissipation
With the high output drive capability of the EL5164, EL5165,
and EL5364, 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 EL5164, EL5165, and EL5364 to
remain in the safe operating area. These parameters are
calculated in Equation 1:
