Overview
The AD8011ARZ, produced by Analog Devices Inc., is a high-speed, low-power current feedback operational amplifier. It is designed to operate on single or dual supplies ranging from +3 V to +12 V, making it versatile for various applications. This amplifier is notable for its wide bandwidth, low distortion, and low power consumption, making it ideal for general-purpose amplification and high-speed portable equipment.
The AD8011ARZ is particularly suited for professional video electronics, such as cameras and video switchers, due to its excellent gain flatness and low differential gain and phase error. Its low power consumption of up to 1.15 mA and small package options (8-lead PDIP or 8-lead SOIC) make it a preferred choice for battery-powered and portable applications.
