GENERAL DESCRIPTION
The AD8091 (single) and AD8092 (dual) are low cost, voltage feedback, high speed amplifiers designed to operate on +3 V, +5 V, or ±5 V supplies. The AD8091/AD8092 have true single supply capability, with an input voltage range extending 200 mV below the negative rail and within 1 V of the positive rail.
Despite their low cost, the AD8091/AD8092 provide excellent overall performance and versatility. The output voltage swing extends to within 25 mV of each rail, providing the maximum output dynamic range with excellent overdrive recovery. This makes the AD8091/AD8092 useful for video electronics, such as cameras, video switchers, or any high speed portable equip ment. Low distortion and fast settling make them ideal for active filter applications.
