General Description

The KH103 is a high-power, wideband op amp designed

for the most demanding high-speed applications. The

wide bandwidth, fast settling, linear phase, and very

low harmonic distortion provide the designer with

the signal fidelity needed in applications such as driving

flash A to Ds. The 80MHz full-power bandwidth and

200mA output current of the KH103 eliminate the

need for power buffers in most applications; the

KH103 is an excellent choice for driving large high-

speed signals into coaxial lines.

In the design of the KH103 special care was taken in

order to guarantee that the output settle quickly to

within 0.4% of the final value for use with ultra fast

flash A to D converters. This is one of the most

demanding of all op amp requirements since settling

time is affected by the op amps bandwidth, passband

gain flatness, and harmonic distortion. This high

degree of performance ensures excellent performance

in many other demanding applications as well.

The dynamic performance of the KH103 is based on a

current feedback topology that provides performance

far beyond that available from conventional op amp

designs. Unlike conventional op amps where optimum

gain-bandwidth product occurs at a high gain, minimum

settling time at a gain of -1, and maximum slew rate

at a gain of +1, the KH103 provides consistent

predictable performance across its entire gain range.

For example, the table below shows how the -3dB

bandwidth remain nearly constant over a wide range

of gains. And since the amplifier is inherently stable,

no external compensation is required. The result is

shorter design time and the ability to accommodate

design changes (in gain, for example) without loss of

performance or redesign of compensation circuits.

The KH103 is constructed using thin film resistor/

bipolar transistor technology, and is available in the

following versions:

-25°C to +85°C

24-pin Ceramic DIP

KH103AK
