GENERAL DESCRIPTION
The AD8051 (single), AD8052 (dual), and AD8054 (quad) are The AD8051/AD8052/AD8054 are well suited for video low cost, high speed, voltage feedback amplifiers. The amplifiers electronics, cameras, video switchers, or any high speed portable operate on +3 V, +5 V, or ±5 V supplies at low supply current. equipment. Low distortion and fast settling make them ideal for They have true single-supply capability with an input voltage active filter applications. range extending 200 mV below the negative rail and within 1 V The AD8051/AD8052 in the 8-lead SOIC, the AD8052 in the of the positive rail. MSOP, the AD8054 in the 14-lead SOIC, and the 14-lead TSSOP Despite their low cost, the AD8051/AD8052/AD8054 provide packages are available in the extended temperature range of excellent overall performance and versatility. The output voltage −40°C to +125°C. swings to within 25 mV of each rail, providing maximum output dynamic range with excellent overdrive recovery.
