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. Display monitors
