The LM1203N is a wideband video amplifier system intended for high resolution RGB color monitor applications. In addition to three matched video amplifiers, the LM1203N contains three gated differential input black level clamp comparators for brightness control and three matched attenuator circuits for contrast control. Each video amplifier contains a gain set or "Drive'' node for setting maximum system gain (Av = 4 to 10) as well as providing trim capability. The LM1203N also contains a voltage reference for the video inputs.
