SPT SPT206AIH, SPT206AMH Datasheet

Package Dimensions

General Description

The SPT206 is a wideband, overdrive-protected operational
amplifier designed for applications needing both speed and high
drive capability (100mA). Utilizing a well-established current
feedback architecture, the SPT206 exhibits performance far
beyond that of conventional voltage feedback op amps. For
example, the SPT206 has a bandwidth of 180MHz at a gain of
+20 and settles to 0.1% in 19ns. Plus, the SPT206 has a
combination of important features not found in other high-speed
op amps.

The 100mA output current and the large signal bandwidth of
70MHz (20Vpp) make the SPT206 ideal for applications which
involve both high signal amplitudes and heavy loads as in coaxial
line driving applications.

Complete overdrive protection has been designed into the
SPT206. This is critical for applications, such as ATE and
instrumentation, which require protection from signal levels high
enough to cause saturation of the amplifier. This feature allows
the output of the op amp to be protected against short circuits
using techniques developed for low-speed op amps. With this
capability, even the fastest signal sources can feature effective
short circuit protection.

The SPT206 is constructed using thin film resistor/bipolar transis­tor technology, and is available in the following versions:
SPT206AIH -25°C to +85°C 12-pin TO-8 can
SPT206AMH -55°C to +125°C 12-pin TO-8 can, features
