MITSUMI RGB Video Amplifier for Monitors MM1203 RGB Video Amplifier for Monitors Monolithic IC MM1203 Outline This IC is a wideband video amplifier system developed for high resolution RGB color monitors. In addition to the three matched video amps, it has three gate control differential input black level comparators for luminance adjustment, and three matched attenuator circuits for contrast adjustment. Each video amp has maximum gain setting (AV=4~10) and a drive pin for trimming. The reference voltage supply for video input is built in. Features 1. Three built-in wideband video amps (70MHz @ -3dB) 2. Current consumption 65mA typ. 3. Matched (±0.5dB) contrast adjustment attenuators built in 4. Built-in luminance adjustment comparators using external gate control 5. Gain of each video amp controlled independently 6. Built-in video input reference voltage 7. Low impedance output driver Package DIP-28B (MM1203ND) Applications 1.
