350MHz Fixed Gain Amplifiers with Enable

Features

• Pb-free Available as an Option

The EL5106 and EL5306 are fixed gain amplifiers with a

bandwidth of 350MHz. 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.

• Gain selectable (+1, -1, +2)

• 350MHz -3dB BW (A = 2)

V

• 1.5mA supply current per amplifier

• Fast enable/disable

With a supply current of just 1.5mA and the ability to run

from a single supply voltage from 5V to 12V, these amplifiers

are also ideal for handheld, portable or battery powered

equipment.

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

• Available in SOT-23 packages

The EL5106 and EL5306 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.

• 450MHz, 3.5mA product available (EL5108 & EL5308)

Applications

• Battery powered equipment

• Handheld, portable devices

• Video amplifiers

The EL5106 is offered in the 6-pin SOT-23 and the industry-

standard 8-pin SO packages and the EL5306 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.

• Cable drivers

• RGB amplifiers

Applications Information

Product Description

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 EL5106

and EL5306 to be enabled by tying CE to ground, even in 5V

single supply applications. The CE pin can be driven from

CMOS outputs.

The EL5106 and EL5306 are fixed gain amplifier that offers

a wide -3dB bandwidth of 350MHz and a low supply current

of 1.5mA. They work with supply voltages ranging from a

single 5V to 12V and they are also capable of swinging to

within 1.2V of either supply on the output. These

combinations of high bandwidth and low power make the

EL5106 and EL5306 the ideal choice for many low-

power/high-bandwidth applications such as portable,

handheld, or battery-powered equipment.

Gain Setting

The EL5106 and EL5306 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 13

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

error is ±2% maximum. Figure 14 shows the amplifier in gain

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

connected together as shown in Figure 15. This

For varying bandwidth and higher gains, consider the

EL5191 with 1GHz on a 9mA supply current or the EL5162

with 300MHz on a 4mA supply current. Versions include

single, dual, and triple amp packages with 5-pin SOT-23,

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

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.

Disable/Power-Down

The EL5106 and EL5306 amplifiers can be disabled placing

their output in a high impedance state. When disabled, the

amplifier supply current is reduced to <25µA. The EL5106

within 1V of the positive supply. Similarly, the amplifier is

Video Performance

Supply Voltage Range and Single-Supply

Operation

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 circuitries have been incorporated in the EL5106 and

EL5306 to reduce the variation of output impedance with

current output. This results in dG and dP specifications of

0.02% and 0.04°, while driving 150Ω at a gain of 2.

The EL5106 and EL5306 have 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 EL5106 and EL5306 will operate on dual supplies

ranging from ±2.5V to ±5V. With single-supply, the EL5106

and EL5306 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

EL5106 and EL5306 have an input range which extends to

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

the EL5106 and EL5306 have an input range which spans

±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 16 shows

an AC-coupled, gain of +2, +5V single supply circuit

configuration.

Output Drive Capability

In spite of its low 1.5mA of supply current per amplifier, the

EL5106 and EL5306 are capable of providing a maximum of

±125mA of output current.

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 EL5106 and EL5306 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.
