Overview
The AD8091ART-REEL7, produced by Analog Devices Inc., is a low-cost, high-speed, voltage feedback operational amplifier. This single-channel amplifier is part of the AD8091 series, which includes the dual-channel AD8092. The AD8091 is designed to operate on a wide range of power supplies, including single supplies from +3 V to +12 V and dual supplies up to ±6 V. It is particularly suited for applications where size, power, and high-speed performance are critical.
The amplifier features a high bandwidth, fast slew rate, and low distortion, making it ideal for various high-speed applications, including video electronics, active filters, and portable equipment. The AD8091 is available in several package options, including the 5-lead SOT-23 (AD8091ART-REEL7), 8-lead SOIC, and MSOP for the AD8092.
