GENERAL 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. 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 equip-
ment. 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).
