LM2408T Monolithic Triple 4.5 ns 50V 22mA CRT Driver IC
The LM2408T is a monolithic triple CRT driver IC specifically developed for high-resolution color display applications. It contains three matched high-speed video amplifiers capable of driving the red, green, and blue cathodes of a color CRT directly. With its fast switching characteristics and wide bandwidth, the LM2408T delivers sharp image quality, excellent color reproduction, and high-definition video performance in CRT monitors and display terminals.
The device integrates three identical amplifier channels in a single package, simplifying circuit design and reducing component count. Its high-voltage output capability and low distortion characteristics make it suitable for computer monitors, video display terminals, medical imaging equipment, industrial displays, and other CRT-based systems requiring accurate RGB signal amplification.
