illustrate
The national LMH6628 is a high speed dual operational amplifier that provides a traditional voltage feedback topology with unity gain stabilization and swing enhancement 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) supply.
The channels of the LMH6628 work closely together to provide a 300MHz unity-gain bandwidth and low input voltage noise density (2nV/). The LMH6628 with low 2nd/3rd harmonic distortion (-65/-74dBc at 10MHz) is a perfectly matched I/Q channel wide dynamic range amplifier.
With its fast, accurate resolution (12ns to 0.1%), the LMH6628 is an excellent choice for wide dynamic range, antialiasing filters, buffers and NiHao resolution analog-to-digital converter inputs. Combining the LMH6628 with two closely matched amplifiers in a single 8-pin SOIC package reduces cost and board space for applications such as active filters for composite amplifiers, differential line drivers/receives, fast peak detectors, and instrumentation amplifiers.
LMH6628 is a VIP10™ free bipolar process using National Semiconductor.
To reduce design time and assist in board layout, support for the LMH6628 is made by the evaluation board (CLC730036).
