Ultrafast Fixed Gain Amplifiers Simplify High Resolution Video Designs

摘要

Whether using composite, S-Video or component video, systems require high performance amplifiers for driving cables, adding gain, converting between formats and shaping the video signals. The increased dimensions of high-definition LCD displays require amplifiers with high gain bandwidth and slew rate to scan the entire screen in one refresh cycle. Low supply voltages present special challenges in video designs, forcing amplifiers to accommodate the video signal's relatively large swings and high slew rates within limited supply rails.
