Additionally, these amplifiers are easy to use and available at a very low cost. Despite their low cost, the AD8055 and AD8056 provide excel- lent overall performance. For video applications, their differen- tial 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 (37.5 Ω). 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. The AD8055 and AD8056 require only 5 mA typ/amplifier of supply current and operate on dual ±5 V or single +12 V power supply, while being capable of delivering over 60 mA of load current. All this is offered in a small 8-lead plastic DIP, 8-lead SOIC packages, 5-lead SOT-23-5 package (AD8055) and an 8-lead microSOIC package (AD8056). These features make the AD8055/AD8056 ideal for portable and battery powered applications where size and power are critical. These amplifiers are available in the industrial temperature range of –40 °C to +85°C.
