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 volt- age swing extends to within 25 mV of each rail, providing the maximum output dynamic range with excellent overdrive recov- ery. This makes the AD8051/AD8052/AD8054 useful for video electronics such as cameras, video switchers or any high speed portable equipment. Low distortion and fast settling make them ideal for active filter applications. The AD8051/AD8052/AD8054 offer low power supply cur- rent and can operate on a single +3 V power supply. These features are ideally suited for portable and battery powered applications where size and power are critical. The wide bandwidth and fast slew rate on a single +5 V supply make these amplifiers useful in many general purpose, high speed applications where dual power supplies of up to ±6 V and single supplies from +3 V to +12 V are needed. All of this low cost performance is offered in an 8-lead SOIC, along with a tiny SOT-23-5 package (AD8051), a µSOIC package (AD8052) and a TSSOP-14 (AD8054).
