AD8054ARU-REEL7

低成本，高速轨到轨放大器 Low Cost, High Speed Rail-to-Rail Amplifiers

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.
