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.
APPLICATIONS
Active Filters
Video Switchers
Distribution Amplifiers
A/D Driver
Professional Cameras
CCD Imaging Systems
Ultrasound Equipment (Multichannel)
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/µs 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 plastic DIP and
SOIC.
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 voltage range
extending 200 mV below the negative rail and within 1 V of the
positive rail.
