EL2126

and video applications. Furthermore, the EL2126 is current-

limited at the output, allowing it to withstand momentary

short to ground. However, the power dissipation with output-

shorted cannot exceed the power dissipation capability of

the package.

where pin 4 (V -) is connected to the ground plane, a single

4.7µF tantalum capacitor in parallel with a 0.1µF ceramic

capacitor across pins 7 (V +) and pin 4 (V -) will suffice.

For good AC performance, parasitic capacitance should be

kept to a minimum. Ground plane construction again should

be used. Small chip resistors are recommended to minimize

series inductance. Use of sockets should be avoided since

they add parasitic inductance and capacitance which will

result in additional peaking and overshoot.

Driving Cables and Capacitive Loads

Although the EL2126 is designed to drive low impedance

load, capacitive loads will decreases the amplifier's phase

margin. As shown in the performance curves, capacitive load

can result in peaking, overshoot and possible oscillation. For

optimum AC performance, capacitive loads should be

reduced as much as possible or isolated with a series

resistor between 5Ω to 20Ω. When driving coaxial cables,

double termination is always recommended for reflection-

free performance. When properly terminated, the

capacitance of the coaxial cable will not add to the capacitive

load seen by the amplifier.

Supply Voltage Range and Single Supply

Operation

The EL2126 has been designed to operate with supply

voltage range of ±2.5V to ±15V. With a single supply, the

EL2126 will operate from +5V to +30V. Pins 4 and 7 are the

power supply pins. The positive power supply is connected

to pin 7. When used in single supply mode, pin 4 is

connected to ground. When used in dual supply mode, the

negative power supply is connected to pin 4.

Power Supply Bypassing And Printed Circuit

Board Layout

As the power supply voltage decreases from +30V to +5V, it

becomes necessary to pay special attention to the input

voltage range. The EL2126 has an input voltage range of

0.4V from the negative supply to 1.2V from the positive

supply. So, for example, on a single +5V supply, the EL2126

has an input voltage range which spans from 0.4V to 3.8V.

The output range of the EL2126 is also quite large, on a +5V

supply, it swings from 0.4V to 3.8V.

As with any high frequency devices, good printed circuit

board layout is essential for optimum performance. Ground

plane construction is highly recommended. Lead lengths

should be kept as short as possible. The power supply pins

must be closely bypassed to reduce the risk of oscillation.

The combination of a 4.7µF tantalum capacitor in parallel

with 0.1µF ceramic capacitor has been proven to work well

when placed at each supply pin. For single supply operation,
