Overview
The AD8055ARTZ-REEL7, produced by Analog Devices Inc., is a single, low-cost, 300 MHz voltage feedback amplifier. This amplifier offers high performance characteristics typically found in current feedback amplifiers, such as wide bandwidth and high slew rate, but with the ease of use and cost-effectiveness of voltage feedback amplifiers. It is available in a 5-lead SOT-23 package, making it ideal for portable and battery-powered applications where size and power are critical.
