PRODUCT DESCRIPTION

The AD8051 (single), AD8052 (dual) and AD8054 (quad) 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 AD8051/AD8052/AD8054 provide

excellent overall performance and versatility. The output volt-

age swing extends to within 25 mV of each rail, providing the

maximum output dynamic range with excellent overdrive recov-

ery. This makes the AD8051/AD8052/AD8054 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 AD8051/AD8052/AD8054 offer low power supply cur-

rent 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 on a single +5 V supply

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,

along with a tiny SOT-23-5 package (AD8051), a SOIC

package (AD8052) and a TSSOP-14 (AD8054).
