The 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 wide dynamic range op amp that operates from a single (5V 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/√Hz). Low 2nd/3rd harmonic distortion (−65/−74dBc at 10MHz) make 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 Texas Instruments' VIP10 complimentary bipolar process.

To reduce design times and assist in board layout, the LMH6628 is supported by an evaluation board (LMH730036).
