Description
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 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/). 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 8-pin SOIC 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 VIP10™ complimentary bipolar process.

To reduce design times and assist in board layout, the LMH6628 is supported by an evaluation board (CLC730036).

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
