Data Sheet
Triple 400MHz Fixed Gain Amplifier with
Enable
The EL5396A is a triple channel, fixed
gain amplifier with a bandwidth of
400MHz, making these amplifiers ideal
for today’s high speed video and monitor applications. The
EL5396A features internal gain setting resistors and can be
configured in a gain of +1, -1 or +2. The same bandwidth is
seen in both gain-of-1 and gain-of-2 applications.
With a supply current of just 9mA per amplifier and the ability
to run from a single supply voltage from 5V to 10V, these
amplifiers are also ideal for hand held, portable or battery
powered equipment.

January 22, 2004
FN7196
Features
• Gain selectable (+1, -1, +2)
• 400MHz -3dB bandwidth (AV = 1, 2)
• 9mA supply current (per amplifier)
• Single and dual supply operation, from 5V to 10V or ±2.5V
to ±5V
• Fast enable/disable
• Power-down
• Available in 16-pin QSOP package
• Single (EL5196) available
• 200MHz, 3mA products available (EL5197 & EL5397)
The EL5396A 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.
For applications where board space is critical, the EL5396A
is offered in the 16-pin QSOP package, as well as a 16-pin
SO (0.150"). The EL5396A is specified for operation over the
full industrial temperature range of -40°C to +85°C.
Applications
• Video amplifiers
• Cable drivers
• RGB amplifiers
• Test equipment
• Instrumentation
• Current to voltage converters

EL5396A
Applications Information
Product Description
The EL5396A is a triple channel fixed gain amplifier that
offers a wide -3dB bandwidth of 400MHz and a low supply
current of 9mA per amplifier. The EL5396A works 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. This combination of high bandwidth and low power,
together with aggressive pricing make the EL5396A the ideal
choice for many low-power/high-bandwidth applications
such as portable, handheld, or battery-powered equipment.
temperature and process, external resistor should not be
used to adjust the gain settings.

For varying bandwidth and higher gains, consider the
EL5191 with 1GHz on a 9mA supply current or the EL5193
with 300MHz on a 4mA supply current. Versions include
single, dual, and triple amp packages with 5-pin SOT23, 16pin QSOP, and 8-pin or 16-pin SO 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.
Disable/Power-Down
The EL5396A amplifier can be disabled placing its output in
a high impedance state. When disabled, the amplifier supply
current is reduced to < 150µA. The EL5396A 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 EL5396A 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 EL5396A to be
enabled by tying CE to ground, even in 5V single supply
applications. The CE pin can be driven from CMOS outputs.
Gain Setting
The EL5396A is built with internal feedback and gain
resistors. The internal feedback resistors have equal value;
as a result, the amplifier can be configured into gain of +1,
-1, and +2 without any external resistors. Figure 1 shows the
amplifier in gain of +2 configuration. The gain error is ±2%
maximum. Figure 2 shows the amplifier in gain of -1
configuration. For gain of +1, IN+ and IN- should be
connected together as shown in Figure 3. This configuration
avoids the effects of any parasitic capacitance on the IN- pin.
Since the internal feedback and gain resistors change with

Supply Voltage Range and Single-Supply
Operation
The EL5396A has been designed to operate with supply
voltages having a span of greater than or equal to 5V and
less than 11V. In practical terms, this means that the
EL5396A will operate on dual supplies ranging from ±2.5V to
±5V. With single-supply, the EL5396A 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
EL5396A has an input range which extends to within 2V of
either supply. So, for example, on ±5V supplies, the
EL5396A has an input range which spans ±3V. The output
range of the EL5396A 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. Figure 4 shows

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.
VOUT
The EL5396A has 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.

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 9mA
supply current of each EL5396A amplifier. Special circuitry
has been incorporated in the EL5396A to reduce the
variation of output impedance with current output. This
results in dG and dP specifications of 0.0035% and 0.04°,
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 EL5396A
has dG and dP specifications of 0.03% and 0.05°,
respectively.
With the high output drive capability of the EL5396A, 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 EL5396A to remain in the safe operating
area. These parameters are calculated as follows:
T JMAX = T MAX + ( θ JA × n × PD MAX )
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 as follows:
V OUTMAX
PD MAX = ( 2 × V S × I SMAX ) + ( V S - V OUTMAX ) × ---------------------------R

Output Drive Capability
In spite of its low 9mA of supply current, the EL5396A is
capable of providing a minimum of ±95mA of output current.
With a minimum of ±95mA of output drive.
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 EL5396A from the cable and allow extensive
capacitive drive. However, other applications may have high
