Notes:

(1) Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only;

functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not

implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

(2) At high closed loop gains and low gain setting resistors care must be taken if large input signals are applied to the device which cause the

output stage to saturate for extended periods of time.

(3) The power dissipation of the device when loaded must be designed to keep the device junction temperature below TJMAX.

*During power-up and power-down, these voltage ratings require that signals be applied only when the power supply is connected.

ESD: This device is sensitive to static discharge and proper handling precautions are required.

APPLICATIONS INFORMATION

Introduction

AtypicalcircuitapplicationisshowninFigure1,above.

This is suitable for 75⍀transmission line connections

at both the input and the output and is useful for

distribution of wide-band signals such as video via

cables. The 75⍀reverse terminating resistor R4 gives

the correct matching condition to a terminated video

cable. The amplifier load is then 150⍀in parallel with

the local feedback network.

The wide bandwidth of this device necessitates some

care in the layout of the printed circuit. A continuous

ground plane is required under the device and its

signal connection paths, to provide the shortest

possible ground return paths for signals and power

supply filtering. A double-sided or multi-layer PCB

construction is required, with plated-through via holes

providing closely spaced low-inductance connections

from some components to the continuous ground

plane.

For the power supply filtering, low inductance surface

mount capacitors are normally required. It has been

found that very good RF decoupling is provided on

each supply using a 1000pF NPO size 0805 or smaller

ceramic surface mount capacitor, closest to the device

pin, with an adjacent 0.1uF X7R capacitor. Other

configurations are possible and it may be found that a

single0.01uF X7Rcapacitor oneach supplygives good

results. However this should be supported by larger

decoupling capacitors elsewhere on the printed circuit

board. Values of 1 to 10µF are recommended,

particularly where the voltage regulators are located

more than a few inches from the device. These larger

capacitors are recommended to be solid tantalum

electrolytic or ceramic types.

Note particularly that the inverting input of this current

feedback type of amplifier is sensitive to small

amounts of capacitance to ground which occur as part

of the practical circuit board layout. This capacitance

affects bandwidth, frequency response peaking and

pulse overshoot. Therefore to minimise this

capacitance, the feedback components R2 and R3 of

Figure1 should be positioned as close as possible to

the inverting input connection.

The frequency response and pulse response will vary

according to particular values of resistors and layout

capacitance. The response can be tailored for the

application to some extent by choice of the value of

feedback resistor. Figure 2 shows an oscilloscope

display of the pulse response for a practical double

sided printed circuit board where RF = 510⍀.
