Data Sheet
Single 400MHz Fixed Gain Amplifier with
Enable
The EL5196 and the EL5196A are
fixed gain amplifiers with a bandwidth
of 400MHz, making these amplifiers
ideal for today’s high speed video and monitor applications.
These amplifiers feature 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.
EL5196, EL5196A
March 12, 2004
Features
• Gain selectable (+1, -1, +2)
• 400MHz -3dB BW (AV = 1, 2)
• 9mA supply current
• Fast enable/disable (EL5196A only)
• Single and dual supply operation, from 5V to 10V or ±2.5V
to ±5V
• Available in SOT-23 packages
The EL5196A 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.
• Triple (EL5396) available
The EL5196 is offered in the 5-pin SOT-23 package and the
EL5196A is available in the 6-pin SOT-23 as well as the
industry-standard 8-pin SO packages. Both operate over the
industrial temperature range of -40°C to +85°C.

EL5196, EL5196A
Applications Information
Product Description
The EL5196 is a fixed gain amplifier that offers a wide -3dB
bandwidth of 400MHz and a low supply current of 9mA per
amplifier. The EL5196 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 EL5196 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 SOT-23, 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 EL5196A amplifier can be disabled placing its output in
a high impedance state. When disabled, the amplifier supply
current is reduced to < 150µA. The EL5196A 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 EL5196A 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 EL5196A 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 EL5196A 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.

Supply Voltage Range and Single-Supply
Operation
The EL5196 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 EL5196
will operate on dual supplies ranging from ±2.5V to ±5V.
With single-supply, the EL5196 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
EL5196 has an input range which extends to within 2V of
either supply. So, for example, on ±5V supplies, the EL5196
has an input range which spans ±3V. The output range of
the EL5196 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
EL5196, EL5196A

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 EL5196 has no internal current-limiting circuitry. If the
output is shorted, it is possible to exceed the Absolute

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 EL5196 amplifier. Special circuitry
has been incorporated in the EL5196 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 EL5196 has
dG and dP specifications of 0.03% and 0.05°, respectively.
With the high output drive capability of the EL5196, 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 EL5196 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 EL5196 is
capable of providing a minimum of ±95mA of output current
with a minimum of ±95mA of output drive.

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 EL5196 from the cable and allow extensive
