The National LMH6628 is a high speed dual op amp that offers a traditional voltage feedback topology featuring unity-gain stability and slew-enhanced circuitry. The LMH6628's low noise and very low harmonic distortion combine to form a very wide dynamic range op amp that operates from a single (5 to 12V) or dual (+5V) power supply. Each of the LMH6628's closely matched channels provides a 300MHz unity gain bandwidth and low input voltage noise density (2nV/SqRtHz). Low 2nd/3rd harmonic distortion (-65/-74dBc at 10MHz) makes the LMH6628 a perfect wide dynamic-range amplifier for matched I/Q channels.
