LM1202 230 MHz Video Amplifier System

Externally gated comparator for brightness control

General Description

0V to 4V high input impedance DC contrast control

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 con-

trolled 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 im-

pedance and operate over a 0V to 4V range for easy inter-

face to bus controlled alignment systems. The LM1202 op-

erates from a nominal 12V supply but can be operated with

supply voltages down to 8V for applications that require re-

duced IC package power dissipation characteristics.
