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.
