Part Details:

LM2445 March 2003 Monolithic LM2445Monolithic Triple 7.5 ns CRT DriverGeneral Description Features The LM2445 is an integrated high voltage CRT driver circuit n Higher gain to match LM126X CMOS preamplifiers designed for use in color monitor applications. The IC con- n 0V to 3.75V input range T tains three high input impedance, wide band amplifiers riple n Stable with 0­20 pF capacitive loads and inductive which directly drive the RGB cathodes of a CRT. Each peaking networks channel has its gain internally set to -20 and can drive CRT n Convenient TO-220 staggered lead package style capacitive loads as well as resistive loads present in other n Maintains standard LM243X Family pinout which is 7.5 applications, limited only by the package s power dissipation. designed for easy PCB layout The IC is packaged in an industry standard 9-lead TO-220molded plastic power package. See the Thermal Consider- ns Applications ations section for more information. n 1024 x 768 displays up to 85 Hz refresh CRT n Pixel clock frequencies up to 95 MHz n Monitors using video blanking Driver Schematic Diagram 20063701 FIGURE 1.
