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:
