1 / 9 page LM2439 Monolithic Triple 9.5 ns CRT Driver General Description The LM2439 is an integrated high voltage CRT driver circuit designed for use in color monitor applications. The IC con- tains three high input impedance, wide band amplifiers which directly drive the RGB cathodes of a CRT. Each chan- nel has its gain internally set to −14 and can drive CRT ca- pacitive loads as well as resistive loads present in other ap- plications, limited only by the package’s power dissipation. The IC is packaged in an industry standard 9-lead TO-220 molded plastic power package. See Thermal Considerations section. Features n Dissipates approximately 50% less power than the LM2406 n Well matched with LM1279 video preamp n 0V to 5V input range n Stable with 0 pF–20 pF capacitive loads and inductive peaking networks n Convenient TO-220 staggered lead package style n Standard LM243X Family Pinout which is designed for easy PCB layout Applications n 1024 x 768 Displays up to 70 Hz Refresh n Pixel clock frequencies up to 75 MHz n Monitors using video blanking Schematic and Connection Diagrams DS100988-1 FIGURE 1.
