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
at 20MHz (2Vpp, RL = 200). The KH207 also provides
-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
versions:
