General Description
The KH206 is a wideband, overdrive-protected
operational amplifier designed for applications
needing both speed and high drive capability
(100mA). Utilizing a well-established current feedback architecture, the KH206 exhibits performance far
beyond that of conventional voltage feedback
op amps. For example, the KH206 has a bandwidth
of 180MHz at a gain of +20 and settles to 0.1% in
19ns. Plus, the KH206 has a combination of important
features not found in other high-speed op amps.
The 100mA output current and the large signal
bandwidth of 70MHz (20Vpp) make the KH206 ideal
for applications which involve both high signal
amplitudes and heavy loads as in coaxial line driving
applications.
Complete overdrive protection has been designed
into the KH206. This is critical for applications, such as
ATE and instrumentation, which require protection
from signal levels high enough to cause saturation of
the amplifier. This feature allows the output of the
op amp to be protected against short circuits using
techniques developed for low-speed op amps. With
this capability, even the fastest signal sources can
feature effective short circuit protection.

transistor technology, and is available in the following
