Figure 5. Low Distortion Rail-to-Rail Output Swing
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.
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.
