The AD8091/AD8092 offer a low power supply current and can operate on a single 3 V power supply. These features are ideally The AD8091 (single) and AD8092 (dual) are low cost, voltage suited for portable and battery-powered applications where size feedback, high speed amplifiers designed to operate on +3 V, and power are critical. +5 V, or ±5 V supplies. The AD8091/AD8092 have true single- supply capability, with an input voltage range extending 200 mV The wide bandwidth and fast slew rate make these amplifiers below the negative rail and within 1 V of the positive rail. useful in many general-purpose, high speed applications where dual power supplies of up to ±6 V and single supplies from +3 Despite their low cost, the AD8091/AD8092 provide excellent V to +12 V are needed. overall performance and versatility. The output voltage swing extends to within 25 mV of each rail, providing the maximum This low cost performance is offered in an 8-lead SOIC output dynamic range with excellent overdrive recovery. This (AD8091/AD8092), a tiny SOT23-5 (AD8091), and an MSOP makes the AD8091/AD8092 useful for video electronics, such (AD8092). as cameras, video switchers, or any high speed portable equip- ment. Low distortion and fast settling make them ideal for active filter applications.
