SPT SPT200AIH, SPT200AMH Datasheet

General Description

The SPT200 operational amplifier achieves performance far
superior to that of other high performance op amps. A current
feedback design provides a bandwidth of DC-95MHz and an
unprecedented settling time of 18nsec to 0.1%. And since thermal
tail has been eliminated, the SPT200 can be depended upon to
settle fast and solidly maintain its level. Drive capability is also
impressive at 24Vpp and 100mA.

Using the SPT200 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 SPT200 offers
predictable response at gain settings from ±1 to ±50. This,
coupled with consistent performance from unit to unit with no
external compensation, makes the SPT200 a real time and cost­saver in design and production situations alike.

Minimizing settling time was a design goal of the SPT200.
Settling time is one of the most demanding of all op amp
requirements since it is affected by the op amp’s bandwidth, gain
flatness, and harmonic distortion. The result of this effort is an
amplifier fast enough for the most demanding high speed D to A
converters and “flash” A to D converters.

The superior slew rate and rise and fall times of the SPT200
make it an ideal amplifier for a broad range of pulse, analog, and
digital applications. Flat gain and phase response from DC to
beyond 50MHz ensure distortion levels well below those of other
op amps. A full power bandwidth of 20MHz eliminates the need
for power buffers in many applications.

The SPT200 is constructed using thin film resistor/bipolar transis­tor technology, and is available in the following versions:
