Working Principle

The BUF04701AIDGSR has a unique topology which enables it to achieve high levels of linearity and power efficiency. This topology utilizes a current feedback architecture (CFA) with a differential input stage. The input stage amplifies the input signal, which is then processed by the CFA. The output stage is composed of a class A driver stage and a class B output stage. The output stage boosts the gain of the signal while keeping distortion low.The BUF04701AIDGSR is designed to provide high-speed video applications with reduced distortion and extended bandwidth. The output stage of the amplifier is capable of providing up to 10A of peak output current, while the differential input stage is designed to provide high input impedance with low noise. The low output noise and fast rise/fall times provide improved video performance, as well as improved power efficiency. Additionally, the output and power stages feature thermal protection and over-current protection to ensure safe operation.

Conclusion

The BUF04701AIDGSR is a versatile and cost-effective linear amplifier for video applications. It provides an excellent combination of linearity, power efficiency, and power density, allowing it to be used in a variety of video-related applications including digital video sampling, photodiode control, camera sensor preamp, and motor control. The unique topology and features of the BUF04701AIDGSR make it a great choice for video applications where performance and efficiency are important.
