PRODUCT DESCRIPTION
The AD8044 is a quad, low power, voltage feedback, high
speed amplifier designed to operate on +3 V, +5 V, or ± 5 V
supplies. It has true single-supply capability with an input volt-
age range extending 200 mV below the negative rail and within
1 V of the positive rail.

TOP VIEW
The output voltage swing extends to within 25 mV of each rail,
providing the maximum output dynamic range. Additionally, it
features gain flatness of 0.1 dB to 12 MHz, while offering differ-
ential gain and phase error of 0.04% and 0.22∞ on a single +5 V
supply. This makes the AD8044 useful for video electronics,
such as cameras, video switchers, or any high speed portable
equipment. The AD8044’s low distortion and fast settling make
it ideal for active filter applications.
The AD8044 offers low power supply current of 13.1 mA max
and can run on a single +3.3 V power supply. These features are
ideally suited for portable and battery-powered applications
where size and power are critical.
The wide bandwidth of 150 MHz, along with 170 V/ms of slew
rate on a single +5 V supply, make the AD8044 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. The AD8044 is available in 14-lead PDIP and
SOIC.
