LM1202

LM1202 230 MHz Video Amplifier System December 1995 LM1202 230 MHz Video Amplifier System General Description The LM1202 is a very high frequency video amplifier system intended for use in high resolution monochrome or RGB color monitor applications In addition to the wideband video amplifier the LM1202 contains a gated differential input black level clamp comparator for brightness control a DC controlled attenuator for contrast control and a DC controlled sub contrast attenuator for drive control The DC control for the contrast attenuator is pinned out separately to provide a more accurate control system for RGB color monitor applications All DC controls offer a high input impedance and operate over a 0V to 4V range for easy interface to bus controlled alignment systems The LM1202 operates from a nominal 12V supply but can be operated with supply voltages down to 8V for applications that require reduced IC package power dissipation characteristics Features Y Wideband video amplifie...
