N-8, R-8, and RM-8 Gain flatness 0.1 dB to 40 MHz 0.01% differential gain error Their 0.1 dB flatness out to 40 MHz, wide bandwidth out to 300 MHz, along with 1400 V/μs slew rate and 20 ns settling time, make them useful for a variety of high speed applications. 0.02° differential phase error Drives 4 video loads (37.5 V) with 0.02% differential Gain and 0.1° differential phase The AD8055 and AD8056 require only 5 mA typ/amplifier of supply current and operate on a dual ±5 V or a single +12 V power supply, while capable of delivering over 60 mA of load current. The AD8055 is available in a small 8-lead PDIP, an 8-lead SOIC, and a 5-lead SOT-23, while the AD8056 is available in an 8-lead MSOP. These features make the AD8055/AD8056 ideal for portable and battery-powered applications where size and power are critical. These amplifiers in the R-8, N-8, and RM-8 packages are available in the extended temperature range of −40°C to +125°C.

Additionally, these amplifiers are easy to use and available at a very low cost. Despite their low cost, the AD8055 and AD8056 provide excellent overall performance. For video applications, their differential gain and phase error are 0.01% and 0.02° into a 150 Ω load and 0.02% and 0.1° while driving four video loads (37.50 Ω). Figure 4. Frequency Response |
