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 AD8091/AD8092 provide excellent over- all performance and versatility. The output voltage swing extends to within 25 mV of each rail, providing the maximum output dynamic range with excellent overdrive recovery. This makes the AD8091/AD8092 useful for video electronics, such as cameras, video switchers, or any high-speed portable equipment. Low distor- tion and fast settling make them ideal for active filter applications. The AD8091/AD8092 offer a low-power supply current 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 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 (AD8091/AD8092), along with a tiny SOT23-5 package (AD8091) and a µSOIC package (AD8092).
