MM1203 is a three-channel video amplifier with wideband characteristics, suitable for high-resolution RGB color monitors, and can independently adjust the gain of each video amplifier, and provide internal video input reference voltage.
The MM1203 is a wide‑band video amplifier system designed for high‑resolution RGB monitors. It integrates three matched video amplifiers, three gate‑control differential input comparators for luminance adjustment, and three matched attenuator circuits for contrast control. Each amp provides independent gain (AV = 4‑10) and includes a drive pin for trimming.
The device is supplied in a DIP‑28 package and operates from a 12 V supply. Typical specifications include 65 mA current consumption, 2.2 V video input reference voltage, 28 mA output current, and a 70‑120 MHz –3 dB bandwidth. Detailed pin functions, absolute maximum ratings, and recommended operating conditions are provided for design reference.
