LM2469 Monolothic Triple 9nS High Gain CRT Driver October 2000 LM2469 Monolothic Triple 9nS High Gain CRT Driver General Description The LM2469 is an integrated high voltage CRT driver circuit designed for use in color monitor applications. The IC contains three high input impedance wide band amplifiers, which directly drive the RGB cathodes of a CRT. Each channel has its gain internally set to -20 and can drive CRT capacitive loads as well as resistive loads present in other applications, limited only by the package’s power dissipation. The IC is packaged in an industry standard 9 lead TO-220 molded plastic package. n 0V to 3.75V input range n Stable with 0-20pF capacitive loads and inductive peaking networks n Maintains standard LM243X Family Pinout which is designed for easy PCB layout n Convenient TO-220 staggered 9 lead package style Applications n Up to 1024 X 768 at 70Hz n Pixel clock frequencies up to 75MHz n Monitors using video blanking Features n Higher gain to match LM126X CMOS preamplifiers Schematic Diagram Connection Diagram DS200006-2 Note: Tab is at GND.
