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. They 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

equipment. Low distortion and fast settling make them ideal for

active filter applications.

The AD8091/AD8092 offer a low power supply current and can

operate on a single 3 V power supply. These features are ideally

suited for portable and battery-powered applications where size

and power are critical.

The wide bandwidth and fast slew rate make these amplifiers

useful in many general-purpose, high speed applications where

dual power supplies of up to ±6 V and single supplies from +3

V to +12 V are needed.

This low cost performance is offered in an 8-lead SOIC

(AD8091/AD8092), along with a tiny SOT23-5 (AD8091) and a

MSOP (AD8092).
