General Description
The KH220 is a wide bandwidth DC-coupled operational
amplifier that defines the state-of-the-art in high
speed op amps. A -3dB bandwidth of DC to 190MHz
is achieved using a current feedback architecture
design. Ultra-fast settling time (8nsec to 0.1%) and
slew rate (7000V/µsec) make the KH220 a superior
amplifier for pulsed and digital applications.
Since thermal tail has been eliminated, the KH220
settles fast and remains solidly at the desired level.
Flat gain and linear phase (1.2° deviation from linear)
from DC to beyond 100MHz help the KH220 to
achieve distortion levels uncommonly low relative to
conventional op amps.
Using the KH220 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
KH220 offers predictable response at gain settings
from ±1 to ±50. This, coupled with consistent perfor-
mance from unit to unit with no external
compensation, makes the KH220 a real time and cost-
saver in design and production situations alike.
This combination of features makes the KH220
appropriate for a broad range of applications. The
wide bandwidth, DC coupling, and fast settling lend
themselves well to high speed D to A and “flash” A to
D applications. Both receivers and transmitters in
optical fiber systems have similar requirements. High
gain and phase linearity and corresponding low
distortion make the KH220 ideal for many digital
communication system applications, such as in the
demodulator, where the need for both DC coupling
and high frequency amplification creates require-
ments that are difficult to meet.
The KH220 is constructed using thin film resistor/bipolar
transistor technology, and available in these versions:
