Engineers interested in precision signal processing will find the HA-51X7, with its unique features, very interesting. Utilizing an advanced design with special device geometries, the HA-51X7 has moved the Intersil dielectric process into a new arena of both speed and precision. Perhaps one of the most remarkable features of the HA-51X7 is its ultra low noise performance, which makes it the first monolithic amplifier to combine speed, precision, and ultra low noise operation (Figure 1).
