AD8005 is an ultralow power, high-speed amplifier. It features ultralow power consumption, high bandwidth, low distortion/noise, etc. It is suitable for signal conditioning, A/D buffering, power-sensitive high-speed systems, battery-powered equipment, communication or video test systems, portable medical instruments, etc.
The AD8005 is a current‑feedback amplifier designed for power‑sensitive, high‑speed systems. It offers a 270 MHz –3 dB bandwidth (gain = +1), 280 V/µs slew rate, and ultralow quiescent current of 400 pA at a +5 V supply, enabling long battery life without sacrificing performance.
The device is supplied in 8‑lead plastic DIP, 8‑lead SOIC and 5‑lead SOT‑23 packages and operates over an industrial temperature range of –40 °C to +85 °C. Typical applications include signal‑conditioning for A/D buffers, portable medical instruments, communication/video test systems, and other battery‑powered high‑speed equipment.
