GENERAL DESCRIPTION

The AD8051 (single), AD8052 (dual), and AD8054 (quad) are

low cost, high speed, voltage feedback amplifiers. The amplifiers

operate on +3 V, +5 V, or ±5 V supplies at low supply current.

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 AD8051/AD8052/AD8054 provide

excellent overall performance and versatility. The output voltage

swings to within 25 mV of each rail, providing maximum output

dynamic range with excellent overdrive recovery.

The AD8051/AD8052/AD8054 are well suited for video

electronics, cameras, video switchers, or any high speed portable

equipment. Low distortion and fast settling make them ideal for

active filter applications.
