APPLICATIONS INFORMATION
chrome monitor The monitor is used with CAD CAM work
stations PCs arcade games and in a wide range of other
applications that benefit from the use of high resolution dis-
play terminals Monitor characteristics may differ in such
ways as sweep rates screen size or in video amplifier
speed but will still be generally configured as shown in Fig-
required or they may be contained as a composite signal in
the video input signal The video input signal is usually

supplied by coaxial cable which is terminated in 75
monitor input and internally AC coupled to the video amplifi-
er The input signal is approximately 1V peak-to-peak in am-
plitude and at the input of the high voltage video section
approximately 6V peak-to-peak At the cathode of the CRT
the video signals can be as high as 60V peak to peak The
block in Figure 4 labeled ‘‘Video Amplification with DC Con-
trolled Gain Black Level’’ contains the function of the
LM1201 video amplifier system
