Overview
The AD8011AR from Analog Devices Inc. is a high-speed, low-power current feedback amplifier designed for a wide range of high-frequency and wideband applications. It operates on a single 5 V or dual ±5 V supply, making it versatile for various power configurations. The amplifier is known for its wide bandwidth, low distortion, and low power consumption, making it ideal for applications requiring high-speed signal processing.
The AD8011AR features a gain flatness of 0.1 dB to 25 MHz, differential gain and phase error of 0.02% and 0.06°, respectively, and a maximum quiescent current of 1.15 mA. This makes it suitable for professional video electronics, high-speed portable equipment, and buffering high-speed A-to-D converters.
