SPT207

LOW DISTORTION WIDEBAND OP AMP

General Description

The SPT207 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 SPT207 offers performance far superior to that
of conventional voltage feedback op amps.

The most attractive feature of the SPT207 is its extremely low
distortion: -80/-85dBc 2nd/3rd harmonics at 20MHz (2Vpp, RL =
200Ω). The SPT207 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,
yet is unity-gain stable without external compensation. The
combination of these features positions the SPT207 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 SPT207 an excel­lent choice. Wide dynamic range systems such as radar and
communication receivers will find that the SPT207’s low harmonic
distortion and low noise make it an attractive high speed solution.

The addition of the SPT207 to the 205/206 Series of high speed
operational amplifiers broadens the selection of features avail­able from which to choose. The SPT205 offers low power
operation, the SPT206 offers higher drive operation, and the
SPT207 offers operation with extremely low distortion, all of
which are pin compatible and overdrive protected.

The SPT207 is constructed using thin film resistor/bipolar transis­tor technology, and is available in the following versions:

SPT207AIH -25°C to +85°C 12-pin TO-8 can
SPT207AMH -55°C to +125°C 12-pin TO-8 can, features burn-
