GENERAL 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 voltage
swing extends to within 25 mV of each rail, providing the maxi-
mum output dynamic range with excellent overdrive recovery.
