General Description  
Y
The LM1212 is a very high frequency video amplifier system  
intended for use in high resolution monochrome or RGB  
color monitor applications with OSD. In addition to the wide-  
band video amplifier the LM1212 contains a gated differen-  
tial input black level clamp comparator for brightness con-  
trol, 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 sepa-  
rately 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–4V range for easy inter-  
face to bus controlled alignment systems. During the OSD
