Video Raster display in High Speed Op Amp applications: Rise and fall times are critically important to the faithful reproduction of video on a raster scan display. The black-to-white luminance signal, (amplitude of a video signal) is such that video amplifiers should be chosen for both bandwidth and slew rate performance. Video signals for distribution are in the range of 1.5 to two volts. To faithfully reproduce video signals of high quality, the overall speed and slew rate must be appropriate. Understanding the slew rate performance is important because in most video designs, the intent is to avoid slew rate limitation in the amplifier. A slew rate condition indicates the feedback control loop is unable to track a portion of the input signal. Video circuits should be designed to avoid this condition, of course. Higher bandwidth, lower settling time, and higher slew rate are all factors in keeping the feedback in operation throughout the input cycle. The clean black-to-white and white-to-black transitions shown on the left-hand side, require the clean drive signal shown below the drawings. Failure to faithfully reproduce the signal on the left due to amplifier limitations will result in the degraded signal shown in the lower right. The signal applied to a video display will produce the degraded result shown in the screen drawing on the upper right-hand corner. A high-quality, high-speed amplifier with video speed, slew rate, and Diff Gain and Diff Phase is crucial to faithful video reproduction.
