The AD8056 (dual) voltage feedback amplifier offers bandwidth and slew rate typically found in current feedback amplifiers. Additionally, this amplifier is easy to use and available at a very low cost.

Despite its low cost, the AD8056 provides excellent overall performance. For video applications, its differential gain and phase error is 0.01% and 0.02° into a 150 Ω load, and 0.02% and 0.1° while driving four video loads (37.50 Ω).

Its 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 AD8056 requires only 5 mA typ/amplifier of supply current and operates on a dual ±5 V or single +12 V power supply, while capable of delivering over 60 mA of load current. The AD8056 is available in a small 8-lead PDIP, 8-lead SOIC, and 8-lead MSOP packages. These features make the AD8056 ideal for portable and battery powered applications where size and power are critical. This amplifier in the R-8, N-8 and RM-8 packages are available in the extended temperature range of -40°C to +125°C.
