General Description

The KH207 is a wideband, low distortion operational

amplifier designed specifically for applications requiring

both high speed and wide dynamic range. Utilizing

a proprietary current feedback architecture, the

KH207 offers performance far superior to that of

conventional voltage feedback op amps.

The most attractive feature of the KH207 is its

extremely low distortion: -80/-85dBc 2nd/3rd harmonics

-3dB bandwidth of 170MHz at a gain of +20, settles to

0.1% in 22ns and slews at a rate of 2400V/

µs. The

combination of these features positions the KH207 as

the right choice for high speed applications requiring

exceptional signal purity.

High speed, high resolution A/D and D/A converter

systems requiring low distortion operation will find

the KH207 an excellent choice. Wide dynamic range

systems such as radar and communication receivers

will find that the KH207’s low harmonic distortion and

low noise make it an attractive high speed solution.

The addition of the KH207 to the KH205/206 Series

of high speed operational amplifiers broadens the

selection of features available from which to choose.

The KH205 offers low power operation, the KH206

offers higher drive operation, and the KH207 offers

operation with extremely low distortion, all of which

are pin compatible and overdrive protected.

The KH207 is constructed using thin film resistor/bipolar

transistor technology, and is available in the following
