EL5160, EL5161, EL5260, EL5261, EL5360

200MHz Low-Power Current Feedback

Amplifiers

The EL5160, EL5161, EL5260, EL5261, and EL5360 are

current feedback amplifiers with a bandwidth of 200MHz and

operate from just 0.75mA supply current. This makes these

amplifiers ideal for today’s high speed video and monitor

applications.

With the ability to run from a single supply voltage from

5V to 10V, these amplifiers are ideal for handheld, portable,

or battery-powered equipment.

The EL5160 also incorporates an enable and disable

function to reduce the supply current to 14µA typical per

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

level will enable the amplifier.

The EL5160 is available in the 6 Ld SOT-23 and 8 Ld SOIC

packages, the EL5161 in 5 Ld SOT -23 and SC-70 packages,

the EL5260 in the 10 Ld MSOP package, the EL5261 in

8 Ld SOIC and MSOP packages, the EL5360 in 16 Ld SOIC

and QSOP packages. All operate over the industrial

temperature range of -40°C to +85°C.

Applications Information

Product Descr iption

The EL5160, EL5161, EL5260, EL5261, and EL5360 are low

power, current-feedback operational amplifiers that offer a

wide -3dB bandwidth of 200MHz and a low supply current of

0.75mA per amplifier. The EL5160, EL5161, EL5260,

EL5261, and EL5360 work 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. Because of their

current-feedback topology, the EL5160, EL5161, EL5260,

EL5261, and EL5360 do not have the normal gain-

bandwidth product associated with voltage-feedback

operational amplifiers. Instead, their -3dB bandwidth to

remain relatively constant as closed-loop gain is increased.

This combination of high bandwidth and low power, together

with aggressive pricing make the EL5160, EL5161, EL5260,

EL5261, and EL5360 ideal choices for many low-

power/high-bandwidth applications such as portable,

handheld, or battery-powered equipment.

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 capacito r in parallel with a 0.01µF ca pacitor has

been shown to work well when placed at each supply pin.

For good AC performance, parasitic capacitance should be

kept to a minimum, especially at the inverting input. (See the

Capacitance at the Inverting Input section) Even when

ground plane construction is used, it should be removed

from the area near the inverting input to minimize any stray

capacitance at that node. Carbon or Metal-Film resistors are

acceptable with the Metal-Film resistors giving slightly less

peaking and bandwidth because of additio nal series

inductance. Use of sockets, particularly for the SO package,

should be avoided if possible. Sockets add parasitic

inductance and capacitance which will result in additional

peaking and overshoot.

Disable/Power-Down

The EL5160 amplifier can be disabled placing its output in a

high impedance state. When disabled, the ampli fie r supply

current is reduced to < 15µA. The EL5160 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 EL5160 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 EL5160 to be enabled by tying CE

to ground, even in 5V single supply applications. The CE pin

can be driven from CMOS outputs.

Capacitance at the Inverting Input

Any manufacturer’s high-speed voltage- or current-feedback

amplifier can be affected by stray capacitance at the

inverting input. For inverting gains, this parasitic capacitance

has little effect because the inverting input is a virtual

ground, but for non-inverting gains, this capacitance (in

conjunction with the feedback and gain resistors) creates a

pole in the feedback path of the amplifie r. This pole, if low

enough in frequency, has the same destabilizing effect as a

zero in the forward open-loop response. The use of large-

value feedback and gain resistors exacerbates the problem

by further lowering the pole frequency (increasing the

possibility of oscillation.)

The EL5160, EL5161, EL5260, EL5261, and EL5360 have

been optimized with a TBDΩ feedback resistor. With the high

bandwidth of these amplifiers, these resistor values might

cause stability problems when combined with parasitic

capacitance, thus ground plane is not recommended around

the inverting input pin of the amplifie r.

Feedback Resistor Values

The EL5160, EL5161, EL5260, EL5261, and EL5360 have

been designed and specified at a gain of +2 with RF

approximately 806Ω. Th is value of fee dback resistor gives

200MHz of -3dB bandwidth at AV = 2 with TBDdB of

peaking. With AV = -2, an RF of approximately TBDΩ gives

200MHz of bandwidth with 1dB of peaking. Since the

EL5160, EL5161, EL5260, EL5261, and EL5360 are current-

feedback amplifiers, it is also possible to change the value of

RF to get more bandwidth. As seen in the curve of

Frequency Response for Various RF and RG, bandwidth and

peaking can be easily modified by varying the value of the

feedback resistor.

Because the EL5160, EL5161, EL5260, EL5261, and

EL5360 are current-feedback amplifiers, their gain-

bandwidth product is not a constant for different closed-loop

gains. This feature actually allows the EL5160, EL5161,

EL5260, EL5261, and EL536 0 to maintain about the same -

3dB bandwidth. As gain is increased, bandwidth decreases

slightly while stability increases. Since the loop stability is

improving with higher closed-loop gains, it becomes possible

to reduce the value of RF below the specified TBDΩ and still

retain stability, resulting in only a slight loss of bandwidth

with increased closed-loop gain.

Supply Voltage Range and Single-Supply

Operation

The EL5160, EL5161, EL5260, EL5261, and EL5360 have

been designed to operate with supply voltages having a

span of greater than 5V and less than 10V. In practical

terms, this means that they will operate on dual supplies

ranging from ±2.5V to ±5V. With single-supply, the EL5160,

EL5161, EL5260, EL5261, and EL5360 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

EL5160, EL5161, EL5260, EL5261, and EL5 360 have an

input range which extends to with in 2V of either supply. So,

for example, on +5V supplies, the EL5160, EL5161, EL5260,

EL5261, and EL5360 have an input range which spans ±3V.

The output range of the EL5160, EL5161, EL5260, EL5261,

and EL5360 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 .

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 outpu t curren t 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 1mA

supply current of each EL5160, EL5161, EL5260, EL5261,

and EL5360 amplifier. Sp ecial circuitry has been

incorporated in the EL5160, EL5161, EL5260, EL5261, and

EL5360 to reduce the variation of output impedance with

current output. This results in dG and dP specifications of

0.1% and 0.1°, 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 EL5160 has

dG and dP specifications of 0.1% and 0.1°.

Output Drive Capability

In spite of their low 1mA of supply current, the EL5160,

EL5161, EL5260, EL5261, and EL5360 are capable of

providing a minimum of ±50mA of output current. With a

minimum of ±50mA of output drive, the EL5160 is capable of

driving 50Ω loads to both rails, making it an excellent choice

for driving isolation transformers in telecommunications

applications.

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 EL5160, EL5161, EL5260, EL5261, and

EL5360 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.

The gain resistor (RG) can then be chosen to make up for

any gain loss which may be created by this additional

resistor at the output. In many cases it is also possible to

simply increase the value of the feedback resistor (RF) to

reduce the peaking.

Current Limiting

The EL5160, EL5161, EL5260, EL5261, and EL5360 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 resultin g in

the destruction of the device.

Power Dissipation

With the high output drive capability of the EL5160, EL5161,

EL5260, EL5261, and EL536 0, it is possibl e 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

EL5160, EL5161, EL5260, EL5261, and EL5360 to remain in

the safe operating area. These parameters are calculated as

follows:

where:

•T

MAX = Maximum ambient te mp era ture

•θJA = Thermal resistance of the package

• n = Number of amplifiers in the package

•PD

MAX = Maximum power dissipation of each amplifier in

the package

PDMAX for each amplifier can be calculated as follows:

where:

•V

S = Supply voltage

•I

SMAX = Maximum supply current of 0.75mA

•V

OUTMAX = Maximum output voltage (required)

•R

L = Load resistance
