This makes the AD8044 useful for video electronics, such as cameras, video switchers, or any high speed portable APPLICATIONS equipment. The AD8044s low distortion and fast settling make Active Filters it ideal for active filter applications. Video Switchers Distribution Amplifiers The AD8044 offers low power supply current of 13.1 mA max A/D Driver and can run on a single +3.3 V power supply. These features are Professional Cameras ideally suited for portable and battery-powered applications CCD Imaging Systems where size and power are critical. Ultrasound Equipment (Multichannel) 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 PRODUCT DESCRIPTION supplies of up to 6 V and single supplies from +3 V to +12 V The AD8044 is a quad, low power, voltage feedback, high are needed. The AD8044 is available in 14-lead PDIP and speed amplifier designed to operate on +3 V, +5 V, or 5 V SOIC. supplies. It has true single-supply capability with an input volt- age range extending 200 mV below the negative rail and within 18 1V of the positive rail.
