1.4GHz Current Feedback Amplifiers with
Enable
The EL5166 and EL5167 amplifiers are of the current
feedback variety and exhibit a very high bandwidth of
1.4GHz at AV = +1 and 800MHz at AV = +2. This makes
these amplifiers ideal for today's high speed video and
monitor applications, as well as a number of RF and IF
frequency designs.
With a supply current of just 8.5mA and the ability to run
from a single supply voltage from 5V to 12V, these amplifiers
offer very high performance for little power consumption.
Features
• Gain-of-1 bandwidth = 1.4GHz/gain-of-2
bandwidth = 800MHz
• 6000V/µs slew rate
• Single and dual supply operation from 5V to 12V
• Low noise = 1.7nV/√Hz
• 8.5mA supply current
• Fast enable/disable (EL5166 only)
• 600MHz family - (EL5164 and EL5165)
The EL5166 also incorporates an enable and disable
function to reduce the supply current to 13µA typical per
amplifier. Allowing the CE pin to float or applying a low logic
level will enable the amplifier.
• 400MHz family - (EL5162 and EL5163)
The EL5167 is offered in the 5 Ld SOT-23 package and the
EL5166 is available in the 6 Ld SOT-23 as well as the
industry-standard 8 Ld SOIC packages. Both operate over
the industrial temperature range of -40°C to +85°C.

Applications Information
Product Description
The EL5166 and EL5167 are current-feedback operational
amplifiers that offers a wide -3dB bandwidth of 1.4GHz and a
low supply current of 8.5mA per amplifier. The EL5166 and
EL5167 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 EL5166 and EL5167 do not have the normal
gain-bandwidth product associated with voltage-feedback
operational amplifiers. Instead, their -3dB bandwidth remains
relatively constant as closed-loop gain is increased. This
combination of high bandwidth and low power, together with
aggressive pricing make the EL5166 and EL5167 ideal
choices for many low-power/high-bandwidth applications,
such as portable, handheld, or battery-powered equipment.
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
“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 EL5166 amplifier can be disabled, placing its output in a
high impedance state. When disabled, the amplifier supply
current is reduced to 13µA. The EL5166 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 EL5166 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 EL5166 to be enabled by tying CE
to ground, even in 5V single supply applications. The CE pin
can be driven from CMOS outputs.

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).
The EL5166 and EL5167 frequency responses are
optimized with the resistor values in Figure 3. 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 EL5166 and EL5167 have been designed and specified
at a gain of +2 with RF approximately 392Ω. This value of
feedback resistor gives 800MHz of -3dB bandwidth at AV = 2
with about 0.5dB of peaking. Since the EL5166 and EL5167
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 in the
“Typical Performance Curves” on page 4, bandwidth and
peaking can be easily modified by varying the value of the
feedback resistor.
Because the EL5166 and EL5167 are current-feedback
amplifiers, their gain-bandwidth product is not a constant for
different closed-loop gains. This feature actually allows the
EL5166 and EL5167 to maintain a reasonably constant -3dB
bandwidth for different gains. 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 250Ω 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 EL5166 and EL5167 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 the EL5166
and EL5167 will operate on dual supplies ranging from
±2.5V to ±5V. With single-supply, they 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
EL5166 and EL5167 have an input range that extends to
within 1.8V of either supply. So, for example, on ±5V
FN7365.6
September 14, 2010
EL5166, EL5167
supplies, the EL5166 and EL5167 have an input range
which spans ±3.2V. The output range of the EL5166 and
EL5167 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.
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 8.5mA supply current of each EL5166 and
EL5167 amplifier. Special circuitry has been incorporated in
the EL5166 and EL5167 to reduce the variation of output
impedance with the current output. This results in dG and
dP specifications of 0.01% and 0.03°, while driving 150Ω at
a gain of 2.
Current Limiting
The EL5166 and EL5167 have no internal current-limiting
circuitry. If the output is shorted, it is possible to exceed the
Absolute Maximum Rating for output current or power
dissipation, potentially resulting in the destruction of the
device.
Power Dissipation
With the high output drive capability of the EL5166 and
EL5167, 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 EL5166 and EL5167 to remain in
the safe operating area. These parameters are calculated as
follows:
T JMAX = T MAX + ( θ JA × n × PD MAX )
where:
Output Drive Capability
TMAX = Maximum ambient temperature
In spite of their low 8.5mA of supply current, the EL5166 and
EL5167 are capable of providing a minimum of ±110mA of
output current. With so much output drive, the EL5166 and
EL5167 are capable of driving 50Ω loads to both rails,
making them an excellent choice for driving isolation
transformers in telecommunications applications.
θJA = Thermal resistance of the package
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 EL5166 and EL5167 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.
