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.
