PRODUCT 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 over-

all 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 distor-

tion 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.

All of this low-cost performance is offered in an 8-lead SOIC

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

(AD8091) and a

µSOIC package (AD8092).
