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.
■ Three wideband video amplifiers (70 MHz @ b3dB)
■ Inherently matched (g0.1 dB or 1.2%) attenuators for contrast control
■ Three externally gated comparators for brightness control
■ Provisions for independent gain control (Drive) of each video amplifier
■ Video input voltage reference
■ Low impedance output driver
