AD8091/AD8092 are low cost, high speed rail-to-rail amplifiers suitable for various applications. They offer high speed and fast settling, low distortion, and outstanding load drive capability.
The AD8091 (single) and AD8092 (dual) are low‑cost, voltage‑feedback, high‑speed amplifiers designed for single‑supply operation at +3 V, +5 V, or up to +12 V. They provide rail‑to‑rail output swing, low distortion, and fast settling, making them suitable for video electronics, active filters, and other high‑speed portable equipment.
Key specifications include a 70‑110 MHz 3 dB bandwidth, 145 V/µs slew rate, 45 ns settling time to 0.1 %, input offset voltage as low as 1 mV, and a quiescent current of about 4.4 mA per amplifier. The devices operate over –40 °C to +85 °C and can drive capacitive loads up to 50 pF.
