The LMH6628 is a high-speed dual op amp from National 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. With its fast and accurate settling (12ns to 0.1%), the LMH6628 is also an excellent choice for wide dynamic range, anti-aliasing filters to buffer the inputs of hi resolution analog-to-digital converters. Combining the LMH6628's two tightly matched amplifiers in a single package reduces cost and board space for many composite amplifier applications such as active filters, differential line drivers/receivers, fast peak detectors and instrumentation amplifiers. The LMH6628 is fabricated using National's VIP 10 (TM) comlimentary bipolar process.
