Overview
The AD8091AR-REEL is a high-speed, low-cost, single voltage feedback operational amplifier produced by Analog Devices Inc. This component is designed to operate on a wide range of power supplies, including +3 V, +5 V, and ±5 V, making it versatile for various applications. The AD8091AR-REEL features a rail-to-rail output and an input voltage range that extends 200 mV below the negative rail and within 1 V of the positive rail, enhancing its usability in single-supply systems. It is packaged in an 8-lead SOIC (Small Outline Integrated Circuit) and is available on a 13-inch tape and reel, which is convenient for automated assembly processes.
