250 MHz Triple Current Feedback Amp w/Disable

Applications Information

nected to the ground plane, a single 4.7 mF tanta-

lum capacitor in parallel with a 0.1 mF ceramic

capacitor across pins 14 and 3 will suffice.

Product Description

The EL2386C is a current-feedback operational

amplifier that offers a wide 3 dB bandwidth of

250 MHz, a low supply current of 3 mA per am-

plifier and the ability to power down to 0 mA. It

also features high output current drive. The

EL2386C can output 55 mA per amplifier. The

EL2386C works with supply voltages ranging

For good AC performance, parasitic capacitance

should be kept to a minimum especially at the

inverting input (see the Capacitance at the In-

verting Input section). Ground plane construc-

tion should be used, but it should be removed

from the area near the inverting input to mini-

mize 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 their additional series

inductance. Use of sockets, particularly for the

SO package should be avoided if possible. Sock-

ets add parasitic inductance and capacitance

which will result in some additional peaking and

overshoot.

from a single 3V to 6V, and it is also capable of

swinging to within 1V of either supply on the

input and the output. Because of its current-feed-

back topology, the EL2386C does not have the

normal gain-bandwidth product associated with

voltage-feedback operational amplifiers. This al-

lows its 3 dB 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

EL2386C the ideal choice for many low-power/

high-bandwidth applications such as portable

computing, HDSL, and video processing.

Disable/Power-Down

The EL2386C amplifier can be disabled, placing

its output in a high-impedance state. When dis-

abled, the supply current is reduced to 0 mA. The

EL2386C is disabled when its ENABLE pin is

floating or pulled up to within 0.5V of the posi-

tive supply. Similarly, the amplifier is enabled by

pulling its ENABLE pin at least 3V below the

For Single and Dual applications, consider the

EL2186C/EL2286C. For Single, Dual and Quad

applications without disable, consider the

EL2180C, EL2280C, or EL2480C, all in industry

standard pin outs. The EL2180C also is available

in the tiny SOT-23 package, which is 28% the

size of an SO8 package. For lower power applica-

tions where speed is still a concern, consider the

EL2170C/EL2176C family which also comes in

similar Single, Dual and Quad configurations

with 70 MHz of bandwidth while consuming

1 mA of supply current per amplifier.

positive supply. For 5V supplies, this means

that an EL2386C amplifier will be enabled when

ENABLE is at 2V or less, and disabled when

ENABLE is above 4.5V. Although the logic lev-

els are not standard TTL, this choice of logic

voltages allows the EL2386C to be enabled by ty-

ing ENABLE to ground, even in

3V single-

supply applications. The ENABLE pin can be

driven from CMOS outputs or open-collector

TTL.

Power Supply Bypassing and Printed

Circuit Board Layout

As with any high-frequency device, good printed

circuit board layout is necessary for optimum

performance. Ground plane construction is high-

ly recommended. 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 4.7 mF tantalum capacitor in

parallel with a 0.1 mF capacitor has been shown

to work well when placed at each supply pin. For

When enabled, supply current does vary some-

what with the voltage applied at ENABLE. For

example, with the supply voltages of the

EL2186C at 5V, if ENABLE is tied to 5V

(rather than ground) the supply current will in-

crease about 15% to 3.45 mA.
