The AD8009 is an ultrahigh speed current feedback amplifier with a phenomenal 5,500 V/µs slew rate that results in a rise time of 545 ps, making it ideal as a pulse amplifier. The high slew rate reduces the effect of slew rate limiting and results in the large signal bandwidth of 440 MHz required for high resolution video graphic systems. Signal quality is maintained over a wide bandwidth with worst-case distortion of –40 dBc @ 250 MHz (G = +10, 1 V p-p). For applications with multitone signals, such as IF signal chains, the third order intercept (3IP) of 12 dBm is achieved at the same frequency. This distortion performance coupled with the current feedback architecture make the AD8009 a flexible component for a gain stage amplifier.
The AD8009 is an ultrahigh‑speed current‑feedback amplifier designed for pulse amplification, high‑resolution video graphics and high‑speed instrumentation. It offers a 5,500 V/µs slew rate, 440 MHz large‑signal bandwidth and very low distortion across a wide frequency range.
The device is available in an 8‑lead SOIC (R‑8) and a 5‑lead SOT‑23 (RT‑5) package, operates from +5 V to 5.5 V, and supports industrial temperature ranges from –40 °C to +85 °C. Typical applications include pulse amplifiers, IF/RF gain stages, high‑resolution video graphics and high‑speed instrumentation.
