Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Type** | Current Feedback Op-Amp | | **Channels** | Dual (2 Amplifiers) | | **Bandwidth (-3 dB)** | 600 MHz ($G = +1$) | | **Slew Rate** | 1200 V/µs | | **Settling Time** | 10 ns to 0.1% | | **Supply Current** | 5.0 mA per amplifier | | **Output Current** | 70 mA | | **Package Type** | SOIC-8 (N-8) | | **Mounting Type** | Surface Mount (SMD) | --- ### 2. Functional Description * **Current Feedback Architecture:** Unlike standard voltage feedback amplifiers, the AD8002 uses current feedback. This allows for a nearly constant bandwidth regardless of the gain, making it ideal for high-speed signals. * **Low Power Consumption:** Despite its high speed, it draws only 50 mW per amplifier on a ±5V supply, which is critical for dense PCB designs where thermal management is a concern. * **Video Performance:** It features a very low differential gain (0.01%) and differential phase (0.02°), ensuring high-quality signal reproduction in video broadcasting and imaging equipment. --- ### 3.
