Typically found in old CRT video circuits, specifically arcade machine display boards
Mitsumi (although a couple of devices are National Semiconductor)
Type: MM1203N
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.
Three built-in wideband video amps (70MHz @ -3dB)
Current consumption 65mA typical
Matched (±0.5dB) contrast adjustment attenuators built in
Built-in luminance adjustment comparators using external gate control
Gain of each video amp controlled independently
Built-in video input reference voltage
Low impedance output driver
Datasheet is supplied (if requested)
