BUF07703PWPRG4 Application Field and Working Principle

BUF07703PWPRG4 is a type of Linear - Amplifiers - Video Amps and Modules. It is a high performance dual-channel video amplifier. It has two amplifiers, each with its own inputs and output for improved channel-to-channel isolation. It features 1.2A fixed current drive, wide bandwidth (typically 25MHz) and high output-voltage swing (typically 200V). And it can also provide up to +20dB of gain.

Application

BUF07703PWPRG4 has a wide range of applications, including switching applications, video signal processing, color and luminance or chrominance processing, RGB color decoding, and line filter applications. It also finds applications in audio, video, image and other signal and audio-visual equipment. As a dual-channel amplifier, it can provide pristine signal transfer in professional audio and video production equipment. Besides that, it can also be used for entertainment displays and home theater equipment. And it can be used for measuring and monitoring signals too.

Working Principle

The BUF07703PWPRG4 video amplifier consists of two amplifiers and two input/output terminals for each amplifier. The power supply for the BUF07703PWPRG4 amplifier is typically a single +5V supply. It has a fixed current sink of 1.2A and uses switchable TTL logic inputs for control. The gain range is from -20dB to +20dB. The output impedance of the amplifier is typically equal to 20 ohms.

The input signals are first amplified by the first amplifier and then fed to the second amplifier. This process is repeated twice to achieve higher gain. The amplifier has a wide bandwidth, typically up to 25MHz, so that it can handle high frequency signals without affecting its output. The common mode rejection ratio of this amplifier is very high, at typically 112dB.

The amplifier also has an input overload protection system to protect its inputs from overload and burnout. The internal protection mechanism of the amplifier allows it to be used in non-linear signal conditioning applications. It has excellent power handling abilities and can provide high signal-to-noise ratios (up to 112dB). The signal-to-noise ratio of the amplifier is about 90dB even when operating at high signal levels.

Conclusion

The BUF07703PWPRG4 video amplifier is a dual-channel amplifier with high performance and wide range of applications. It has wide bandwidth and high output-voltage swing capabilities, along with excellent input overload protection system. It can be used in non-linear signal conditioning applications and in professional audio and video production equipment. It provides superior signal-to-noise ratio and power handling abilities.
