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:
