AD8055:  Low Cost, Single, 300 MHz Voltage Feedback Amplifier

Product Description

The AD8055 (single) 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 AD8055 provides excellent overall performance. For video applications, its differential gain and phase error is 0.01% and 0.02° into a 150 W load, and 0.02% and 0.1° while driving four video loads (37.50 W).

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 AD8055 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 AD8055 is available in a small 8-lead PDIP, 8-lead SOIC, and 5-lead SOT-23 packages. These features make the AD8055 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.

AD8055 (Single) PDIP-8, SOIC-8 and SOT-23-5
