Overview
The AD813ARZ-14 is a low power, single supply triple video amplifier manufactured by Analog Devices Inc. This component is designed to optimize performance in video and high-speed applications. Each of the three current feedback amplifiers has 50 mA of output current and is optimized for driving one back-terminated video load (150 Ω). The AD813 features excellent video specifications, including gain flatness of 0.1 dB to 50 MHz and differential gain and phase error of 0.03% and 0.06°, respectively. It operates on a single +3 V to +15 V power supply and is suitable for both portable and battery-powered applications due to its low power consumption of 5.5 mA per amplifier.
