450MHz Fixed Gain Amplifiers with Enable

Features

• Pb-free Available as an Option

The EL5108 and EL5308 are fixed gain amplifiers with a

bandwidth of 450MHz. This makes these amplifiers ideal for

today’s high speed video and monitor applications. They

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.

• Gain selectable (+1, -1, +2)

• 450MHz -3dB BW (A = -1, +1, +2)

• 3.5mA supply current per amplifier

• Single and dual supply operation, from 5V to 12V

• Available in SOT-23 packages

The EL5108 and EL5308 also incorporate an enable and

disable function to reduce the supply current to 25µA typical

per amplifier. Allowing the CE pin to float or applying a low

logic level will enable the amplifier.

• 350MHz, 1.5mA product available (EL5106 & EL5306)

Applications

The EL5108 is offered in the 6-pin SOT-23 and the industry-

standard 8-pin SO packages and the EL5308 is available in

the 16-pin SO and 16-pin QSOP packages. All operate over

the industrial temperature range of -40°C to +85°C.

Disable/Power-Down

Applications Information

The EL5108 and EL5308 amplifiers can be disabled and

placing their outputs in a high impedance state. When

disabled, the amplifier supply current is reduced to <25µA.

The EL5108 and EL5308 are disabled when the 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 the 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 allow the

EL5108 and EL5308 to be enabled by tying CE to ground,

even in 5V single supply applications. The CE pins can be

driven from CMOS outputs.

Product Description

The EL5108 and EL5308 are fixed gain amplifiers that offer a

wide -3dB bandwidth of 450MHz and a low supply current of

3.5mA per amplifier. They work with supply voltages ranging

from a single 5V to 10V and they are also capable of

swinging to within 1.2V of either supply on the output. These

combinations of high bandwidth, low power, and high slew

rate make the EL5108 and EL5308 the ideal choice for many

low-power/high-bandwidth applications such as portable,

handheld, or battery-powered equipment.

For varying bandwidth and higher gains, consider the

EL5166 with 1GHz on a 9mA supply current or the EL5164

with 600MHz on a 3.5mA supply current. Versions include

single, dual, and triple amp packages with 6-pin SOT-23,

16-pin QSOP, and 8-pin or 16-pin SO outlines.

Gain Setting

The EL5108 and EL5308 are 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 21

shows the amplifier in gain of +2 configuration. The gain

error is ±2% maximum. Figure 22 shows the amplifier in gain

of -1 configuration. For gain of +1, IN+ and IN- should be

connected together as shown in Figure 23. This

configuration avoids the effects of any parasitic capacitance

on the IN- pin. Since the internal feedback and gain resistors

change with temperature and process, external resistor

should not be used to adjust the gain settings.

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.

325Ω

FIGURE 21. A = +2

EL5108, EL5308

Video Performance

325Ω

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).

Special circuitry has been incorporated in the EL5108 and

EL5308 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.

Output Drive Capability

In spite of its low 3.5mA of supply current per amplifier, the

EL5108 and EL5308 are capable of providing a maximum of

±130mA of output current.

Supply Voltage Range and Single-Supply

Operation

The EL5108 and EL5308 have been designed to operate

with supply voltages having a span of greater than or equal

to 5V and less than 12V. In practical terms, this means that

they will operate on dual supplies ranging from ±2.5V to ±5V.

With single-supply, they will operate from 5V to 10V.

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 EL5108 and EL5308 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.

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

EL5108 and EL5308 have an input range which extends to

within 2V of either supply. So, for example, on ±5V supplies,

the input range is about ±3V. The output range 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 24 shows an AC-coupled, gain of

+2, +5V single supply circuit configuration.

Current Limiting

The EL5108 and EL5308 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

325Ω

With the high output drive capability of the EL5108 and

EL5308, it is possible to exceed the 125°C Absolute

Maximum junction temperature under certain very high load

current conditions. Generally speaking when R falls below

about 25Ω, it is important to calculate the maximum junction

4.7µF

temperature (T

) for the application to determine if
