General Description

The LM1203 is a wideband video amplifier system intended for high-resolution RGB color monitor applications. In addition to three matched video amplifiers, the LM1203 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 e 4 to 10) as well as providing trim capability. The LM1203 also contains a voltage reference for the video inputs. For high-resolution monochrome monitor applications see the LM1201 Video Amplifier System datasheet.
