The LM1203 is a wideband video amplifier system intender for high-resolution RGB color monitor applications. In addition to three matched video amplifiers, the LM1203 contains three gated differential input black level clamp comparators for brightness control and three matched attenuator circuits for contrast control. Each video amplifier contains again set or ‘‘Drive’’ node for setting maximum system gain as well as providing trim capability. The LM1203 also contains a voltage reference for the video inputs.
