AD8051 Low Cost, High Speed, Single, Rail-to-Rail Amplifier

Active filters Analog-to-digital drivers Clock buffer Consumer video Professional cameras CCD imaging systems CD/DVD ROMs

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 the 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.

The AD8051/AD8052 in the 8-lead SOIC, the AD8052 in the MSOP, the AD8054 in the 14-lead SOIC, and the 14-lead TSSOP packages are available in the extended temperature range of −40°C to +125°C.
