Description

The AD8056ARMZ is a dual voltage feedback amplifier that belongs to the instrumentation OpAmps product category. It is designed to offer a bandwidth and slew rate commonly found in current feedback amplifiers. The amplifier is incredibly easy to use and available at a low cost but delivers exceptional performance. Its differential gain and phase error is 0.01% and 0.02° into a 150 Ω load for video applications. Furthermore, its cost-effectiveness doesn't compromise its excellent overall performance.
