General Description
The KH205 is a wideband overdrive-protected opera-
tional amplifier designed for applications needing
both speed and low power operation. Utilizing a
well-established current feedback architecture, the
KH205 exhibits performance far beyond that of
conventional voltage feedback op amps. For example,
the KH205 has a bandwidth of 170MHz at a gain of
+20 and settles to 0.1% in 22ns. Plus, the KH205 has
a combination of important features not found in
other high-speed op amps.
For example, the KH205 has been designed to consume
little power – 570mW at ±15V supplies. The result is
lower power supply requirements and less system-
level heat dissipation. In addition, the device can be
operated on supply voltages as low as ±5V for even
lower power dissipation.
Complete overdrive protection has been designed
into the part. 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.
The KH205 is constructed using thin film resistor/bipolar
transistor technology, and is available in the following
