The ISL59440IA-T7 Linear Video Amplifier is an easy to use, high quality video amplifier ideal for video buffers and signal processing applications. It offers low distortion, high output current and a wide bandwidth, making it well-suited for numerous video processing applications including line buffers, digital signal processors and signal multipliers. This video amplifier comes in two varieties: a dual version for use in signal line repeaters and a quad version for signal distribution. It is capable of amplifying both standard (NTSC and PAL) and high definition (1080p/i and 720p/i) video signals.

Working Principle
The basic principle behind the ISL59440IA-T7 Linear Video Amplifier is a transresistance amplifier with an open-loop gain of about 74,000. This means that the video amplifier is able to respond to small changes in video signal level quickly, resulting in an improved signal-to-noise ratio and improved fidelity. The input is given differential feedback. This gives the amplifier high gain and helps to suppress common mode noise. The output stage is an output buffer which has a high slew rate. This helps to reduce harmonic distortion.

Application Field
This video amplifier is designed to be used in a variety of video processing applications. It is ideal for buffering, distributing, or processing video signals. It is recommended for use in applications such as line buffers, digital signal processors, signal amplifiers, and switch-mode power amplifiers. Additionally, the ISL59440IA-T7 can be used to process composite and component video signals, including those from NTSC and PAL sources. It can also be used for digital video, such as those from AVCHD camcorders. Furthermore, it is ideal for applications using both high definition (1080p/720p/i) and baseband (NTSC/PAL) signals, as it can amplify each without interfering with the other.

The ISL59440IA-T7 Linear Video Amplifier is a practical and accessible tool for numerous video processing applications. It features a low distortion, wide bandwidth, and high-output current to ensure reliable and accurate signal processing. It is ideal for applications that require both high definition and baseband video signal amplification, making it an invaluable asset for professional and consumer video production workflows.
