LM2469
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 0-20p F 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
