PRODUCT DESCRIPTION
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. 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).
