General Description
The KH200 operational amplifier achieves performance
far superior to that of other high performance op
amps. A current feedback design provides a band-
width of DC-95MHz and an unprecedented settling
time of 18nsec to 0.1%. And since thermal tail has
been eliminated, the KH200 can be depended upon
to settle fast and solidly maintain its level. Drive
capability is also impressive at 24V
pp
and 100mA.
Using the KH200 is as easy as adding power supplies
and a gain-setting resistor. The result is reliable,
consistent performance because such characteristics as
bandwidth and settling time are virtually independent
of gain setting. Unlike conventional op amp designs
where the optimum gain bandwidth product occurs at
a high gain, minimum settling time at a gain of -1,
maximum slew rate at a gain of +1, et cetera,
the KH200 offers predictable response at gain
settings from ±1 to ±50. This, coupled with consistent
performance from unit to unit with no external com-
pensation, makes the KH200 a real time and cost-
saver in design and production situations alike.
Minimizing settling time was a design goal of the
KH200. Settling time is one of the most demanding of
all op amp requirements since it is affected by the
op amp’s bandwidth, gain flatness, and harmonic
distortion. The result of this effort is an amplifier fast
enough for the most demanding high speed D to A
converters and “flash” A to D converters.
The superior slew rate and rise and fall times of the
KH200 make it an ideal amplifier for a broad range of
pulse, analog, and digital applications. Flat gain and
phase response from DC to beyond 50MHz ensure
distortion levels well below those of other op amps. A
full power bandwidth of 20MHz eliminates the need
for power buffers in many applications.

transistor technology, and is available in the following
