Overview
The AD813AR-14, produced by Analog Devices Inc., is a low power, single supply triple video amplifier. This component is designed to optimize performance in video and high-speed applications. Each of the three current feedback amplifiers has an output current of 50 mA and is optimized for driving one back-terminated video load (150 Ω). The AD813AR-14 is notable for its low power consumption, operating with a maximum of 5.5 mA per amplifier, and it can run on a single +3 V or +5 V power supply. This makes it ideal for portable and battery-powered applications where size and power are critical.
