Technical details

The 5 V to 12 V supply span gives flexibility: run it on a single 5 V rail for a 2 Vpp output swing, or go to ±5 V for a wider dynamic range. No compensation pin is needed; current-feedback amps are inherently stable at the gain set by the feedback resistor value, which the datasheet recommends for a given bandwidth target.

For a high-speed op-amp in a small SOT-23-6, that means the design is not locked to a surplus channel; standard distribution handles it.

Package and mounting — SOT-23-6 footprint

Surface-mount in a SOT-23-6 package (supplier device package same as the case code).

Where it is used

Typical applications include high-speed ADC driver stages, video distribution amplifiers, cable drivers, pulse generators, and IF amplifier chains in communications receivers. The industrial temperature range suits outdoor telecom cabinets, factory automation sensor interfaces, and test equipment that sees ambient swings.
