The **AD8005ART-R2** is a high-speed, low-power current feedback operational amplifier manufactured by Analog Devices. It is specifically designed for applications requiring high performance with minimal power consumption. --- ## 1. Core Technical Specifications The following table outlines the key electrical characteristics of the AD8005ART-R2: | Parameter | Specification | | :--- | :--- | | **Architecture** | Current Feedback Op-Amp | | **Bandwidth (-3 dB)** | 270 MHz | | **Slew Rate** | 1500 V/µs | | **Quiescent Current** | 400 µA (Typical) | | **Supply Voltage Range** | ±1.5 V to ±6 V (or 3V to 12V single) | | **Settling Time (0.1%)** | 10 ns | | **Output Current** | 10 mA | | **Package Type** | SOT-23-5 (Small Outline Transistor) | --- ## 2. Key Features and Advantages ### Low Power Consumption One of the most significant aspects of this part is its **400 µA** quiescent current. This makes it ideal for battery-operated portable devices where power efficiency is critical, without sacrificing the speed typical of high-end op-amps. ### High-Speed Performance Despite its low power draw, it offers a **270 MHz bandwidth** and a massive **1500 V/µs slew rate**. This allows the component to handle fast-rising pulses and high-frequency signals with minimal distortion. ### Current Feedback Architecture Unlike standard voltage feedback amplifiers, the current feedback architecture of the AD8005 allows the closed-loop bandwidth to remain relatively constant regardless of the gain setting. --- ## 3.
