600MHz Current Feedback Amplifiers with Enable
EL5164, EL5165, EL5364
Features
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.
• 600MHz -3dB bandwidth
With a supply current of just 3.5mA per amplifier and the
ability to run from a single supply voltage from 5V to 12V,
these amplifiers are also ideal for handheld, portable or
battery-powered equipment.
The EL5164 and EL5364 also incorporate 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, enables the amplifier.
The EL5165 is offered in the 5 Ld SOT-23 package, 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.
• 4700V/µs slew rate
• 3.5mA supply current
• Single and dual supply operation, from 5V to 12V supply span
• Fast enable/disable (EL5164 and EL5364 only)
• Available in SOT-23 packages
• High speed, 1.4GHz product available (EL5166 and EL5167)
• 500MHz products available in Single (EL5162, EL5163), Dual
(EL5262, EL5263) and Triple (EL5362)
• Pb-Free (RoHS compliant)
Applications
• Video amplifiers
• Cable drivers
• RGB amplifiers
• Test equipment
• Instrumentation
• Current to voltage converters

Product Description
The EL5164, EL5165, and EL5364 are current-feedback operational
amplifiers that offer a wide -3dB bandwidth of 600MHz and a low
supply current of 3.5mA 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 gainbandwidth product associated with voltage-feedback operational
amplifiers. Instead, their -3dB bandwidth remains relatively
constant as closed-loop gain increases. This combination of high
bandwidth and low power, together with aggressive pricing makes
the EL5164, EL5165, and EL5364 ideal choices for many lowpower/high-bandwidth applications such as portable, handheld, or
battery-powered equipment. For varying bandwidth needs, consider
the EL5166 and EL5167 with 1.4GHz bandwidth and an 8.5mA
supply current, or the EL5162 and EL5163 with 500MHz bandwidth
and a 1.5mA supply current. Versions include single, dual, and triple
amp configurations with 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 results in additional peaking and overshoot.

Disable/Power-Down
The EL5164 and EL5364 amplifiers can be disabled, placing
their outputs in a high impedance state. When disabled, the
amplifiers supply current reduces to <25µA per amplifier. An
amplifier disables 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 a
±5V supply, this means that an amplifier enables when its CE is
2V or less, and disables when CE is above 4V. Although the logic
levels are not standard TTL, this choice of logic voltages allows
the amplifiers 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 noninverting 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.)
The EL5164, EL5165, and EL5364 are optimized for a 510Ω
feedback resistor at AV = +1. 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 EL5164, EL5165, and EL5364 have been designed and
specified for a gain of +2 with RF approximately 412Ω. This value
of feedback resistor gives 450MHz of -3dB bandwidth at AV = 2
with 1dB 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
curves of “Frequency Response for Various RF”, bandwidth and
10
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 412Ω and still retain stability, resulting
in only a slight loss of bandwidth with increased closed-loop gain.
Supply Voltage Range and Single-Supply
Operation
The EL5164, EL5165, and EL5364 are designed to operate with
supply voltages having a span of 5V to 10V. In practical terms,
this means that they will operate on dual supplies ranging from
±2.5V to ±5V. With a 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. 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. Singlesupply 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 must 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 3.5mA supply
current of each EL5164, EL5165, and EL5364 amplifier. 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
where:
In spite of their low 3.5mA of supply current, the EL5164, EL5165,
and EL5364 are capable of providing a minimum of ±100mA of
output current. With a minimum of ±100mA 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.

Typical Application Circuits
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 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 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.

The EL5164, EL5165, and EL5364 have no internal output

device.
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 to remain
in the safe operating area. These parameters are calculated in
