低成本，高速轨到轨放大器 Low Cost, High Speed Rail-to-Rail Amplifiers
Product Details
The AD8091 single and AD8092 dual are low cost, voltage feedback, high speed amplifiers designed to operate on +3 V, +5 V, or ±5 V supplies. The AD8091/AD8092 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 overall 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 distortion 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.
This low cost performance is offered in an 8-lead SOIC AD8091/AD8092, a tiny SOT23-5 AD8091, and an MSOP AD8092.
