MAX9587AZT+T Application Field and Working Principle

The MAX9587AZT+T is a packaged combination of an active Video Splitter, Video adder/subtractor, and a Video Amplifier. The package known as a Video Amplifier Module, or VAM, is designed for a broad range of analog video applications. This article will explore the application field and working principle of the MAX9587AZT+T.

Application Field

The MAX9587AZT+T is an excellent choice for a range of video applications. The Video Splitter is an ideal device for splitting off an analog video signal into multiple outputs. It can be used in video production, duplication, and distribution applications as well as in video monitoring systems. The Video adder/subtractor offers a video signal with additional functionality. It is capable of adding two video signals together to create a composite signal and subtracting a video signal from a reference signal to create a difference signal. This makes the MAX9587AZT+T ideal for video surveillance, broadcast applications and special effects in movies or television. Finally, the Video Amplifier can boost the amplitude of a video signal with minimal compression or distortion. This makes it perfect for noisy environments such as TV rooms, bars, or cabins.

Working Principle

The MAX9587AZT+T consists of three independent circuits. The Video Splitter divides an incoming video signal into two or three video outputs. It uses a pair of matched high-steepness amplifiers, one for each output, to ensure the highest fidelity. The Video adder/subtractor is slightly more complex: it uses two double-balanced modulators (DBMs) to perform various operations on incoming video signals. The Video Amplifier serves to boost the amplitude of the video signals. It consists of a differential input stage, a gain amplifier, and an output driver. The differential input stage removes any common-mode signals from the output. The Gain amplifier amplifies the signal and the output driver buffers the signal for its transmission.

Conclusion

The MAX9587AZT+T Video Amplifier Module is an innovative device designed for a variety of analog video applications. It consists of three independent circuits: a Video Splitter, a Video adder/subtractor, and a Video Amplifier. The Video Splitter is used in video production, duplication and distribution. The Video adder/subtractor adds two video signals together to create a composite signal and subtracts a video signal from a reference signal to create a difference signal. Finally, the Video Amplifier boosts the amplitude of a video signal with minimal compression or distortion. Together these circuits provide a powerful and precise solution for a variety of video applications.
