650MHz, Gain of 5, Low Noise Amplifiers
Features
• 650MHz -3dB bandwidth
The EL5134, EL5135, EL5234, and EL5235 are ultra-low
voltage noise, high speed voltage feedback amplifiers that
are ideal for applications requiring low voltage noise,
including communications and imaging. These devices offer
extremely low power consumption for exceptional noise
performance. Stable at gains as low as 5, these devices offer
100mA of drive performance. Not only do these devices find
perfect application in high gain applications, they maintain
their performance down to lower gain settings.
• Av=+5 stable
• Ultra low noise 1.5nV/√Hz and 0.9pA/√Hz
• 450V/µs slew rate
• Low supply current = 6.7mA per amplifier
• Single supplies from 5V to 12V
• Dual supplies from ±2.5V to ±5V
• Fast disable on the EL5134 and EL5234
• Duals EL5234 and EL5235
• Low cost
These amplifiers are available in small package options
(SOT-23) as well as the MSOP and the industry-standard
SO packages. All parts are specified for operation over the
-40°C to +85°C temperature range.
• Pb-free plus anneal available (RoHS compliant)
Applications
• Imaging
• Instrumentation
• Communications devices

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL classified
at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.

Product Des cription
The EL5134, EL5135, EL5234 and EL5235 are voltage
feedback operational amplifiers designed for communication
and imaging applications requiring very low voltage and
current noise. They also feature low distortion while drawing
moderately low supply current and is built on Intersil's
proprietary high-speed complementary bipolar process. The
EL5134, EL5135, EL5234 and EL5235 use a classical
voltage-feedback topology which allows them to be used in a
variety of applications where current-feedback amplifiers are
Gain-Bandwidth Product and the -3dB Bandwidth
The EL5134, EL5135, EL5234 and EL5235 have a gain-
bandwidth product of 1500MHz while using only 6.7mA of
supply current per amplifier. For gains greater than 5 their
closed-loop -3dB bandwidth is approximately equal to the
gain-bandwidth product divided by the noise gain of the
circuit. For gains of 5, higher-order poles in the amplifiers'

transfer function contribute to even higher closed loop
±2.5V to ±6V. With single-supply, the EL5134, EL5135,
EL5234 and EL5235 will operate from 5V to 12V. To prevent
internal circuit latch-up, the slew rate between the negative
and positve supplies must be less than 1V/nS.
bandwidths. For example, the EL5134, EL5135, EL5234 and
EL5235 have a -3dB bandwidth of 650MHz at a gain of 5,
dropping to 150MHz at a gain of 10. It is important to note
that the EL5134, EL5135, EL5234 and EL5235 is designed
so that this “extra” bandwidth in low-gain application does
not come at the expense of stability. As seen in the typical
performance curves, the EL5134, EL5135, EL5234 and
EL5235 in a gain of only 5 exhibited 0.2dB of peaking with a
500Ω load.
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
EL5134, EL5135, EL5234 and EL5235 have an input range
which extends to within 2V of either supply. So, for example,
on ±5V supplies, the EL5134, EL5135, EL5234 and EL5235
have an input range which spans ±3V. The output range of
the EL5134, EL5135, EL5234 and EL5235 is also quite
large, extending to within 2V of the supply rail. On a ±5V
supply, the output is therefore capable of swinging from
-3.1V to +3.1V. Single-supply output range is larger because
of the increased negative swing due to the external pull-
down resistor to ground.
Output Drive Capability
The EL5134, EL5135, EL5234 and EL5235 are designed to
drive a low impedance load. They can easily drive 6V
P-P
signal into a 500Ω load. This high output drive capability
makes the EL5134, EL5135, EL5234 and EL5235 and ideal
choice for RF, IF, and video applications. Furthermore, the
EL5134, EL5135, EL5234 and EL5235 are current-limited at
their outputs, allowing them to withstand momentary short to
ground. However, the power dissipation with output-shorted
cannot exceed the power dissipation capability of the
package.
Power Dis s ipation
With the wide power supply range and large output drive
capability of the EL5134, EL5135, EL5234 and EL5235, it is
possible to exceed the 150°C maximum junction
temperatures under certain load and power-supply
conditions. It is therefore important to calculate the
Driving Cables and Capacitive Loads
Although the EL5134, EL5135, EL5234 and EL5235 are
designed to drive low impedance load, capacitive loads will
decreases the amplifiers’ phase margin. As shown in the
performance curves, capacitive load can result in peaking,
overshoot and possible oscillation. For optimum AC
performance, capacitive loads should be reduced as much
as possible or isolated with a series resistor between 5Ω to
20Ω. When driving coaxial cables, double termination is
always recommended for reflection-free performance. When
properly terminated, the capacitance of the coaxial cable will
not add to the capacitive load seen by the amplifier.

for each amplifier can be calculated as follows:
The EL5134 and EL5234 amplifiers can be disabled placing
their outputs in a high impedance state. When disable, each
amplifier current is reduced to 12uA. The EL5134 and
EL5234 are disabled when their CE pins are pulled up to
within 1V of the power suply. Similarly, the amplifiers are
enabled by floating or pulling its CE pin to at least 3V below
the positive supply. For +/-5V supply, this means that
EL5134 and EL5234 amplifiers will be enabled when CE is
2V or less, and disabled when CE is above 4V. Although the
logic levels are not stardard TTL, this choice of logic
voltages allows the EL5134 and EL5234 to be enabled by
typing CE to ground, even in 5V single supply applications.
The CE pin can be driveing from CMOS outputs.

plane construction is highly recommended. Pin lengths
should be kept as short as possible. The power supply pins
must be closely bypassed to reduce the risk of oscillation.
The combination of a 4.7µF tantalum capacitor in parallel
with 0.1µF ceramic capacitor has been proven to work well
when placed at each supply pin. For single supply operation,
where pin 4 (V -) is connected to the ground plane, a single

For good AC performance, parasitic capacitance should be
kept to a minimum. Ground plane construction again should
be used. Small chip resistors are recommended to minimize
series inductance. Use of sockets should be avoided since
they add parasitic inductance and capacitance which will
result in additional peaking and overshoot.
