Overview
The AD8055ART-R2, produced by Analog Devices Inc., is a low-cost, single-channel voltage feedback amplifier. It offers a unique combination of high bandwidth and slew rate, typically found in current feedback amplifiers, but with the ease of use of voltage feedback amplifiers. This amplifier is particularly suited for high-speed applications, including video and imaging systems, due to its excellent performance characteristics.
The AD8055ART-R2 operates on a dual ±5 V or single +12 V power supply, consuming only 5 mA of supply current per amplifier. It is available in several package options, including an 8-lead PDIP, 8-lead SOIC, and a 5-lead SOT-23, making it ideal for portable and battery-powered applications where size and power efficiency are critical.
