描述 Description

General Description
The LM1203A is an improved version of the popular LM1203 wideband video amplifier system. The device is intended for high resolution RGB CRT monitors. In addition to three matched video amplifiers, the LM1203A 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 or providing gain trim capability for white balance. The LM1203A also contains a voltage reference for the video inputs. The LM1203A is pin and function compatible with the LM1203.
