1 / 11 page LM2412 Monolithic Triple 2.8 ns CRT Driver General Description The LM2412 is an integrated high voltage CRT driver circuit designed for use in high resolution color monitor applica- tions. 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 −14 and can drive CRT capacitive loads as well as resistive loads pre- sented by other applications, limited only by the package’s power dissipation. The LM2412 is a low power alternative of the LM2402 The IC is packaged in an industry standard 11 lead TO-220 molded plastic power package. See thermal considerations section for heat sinking requirements. Features n Rise/fall times typically 2.8 ns with 8 pF load at 40 VPP n Lower power than LM2402 with the same bandwidth n Well matched with LM2202 video preamps n Output swing capability: 50 VPP for VCC = 80V n 1V to 5V input range n Stable with 0-20 pF capacitive loads and inductive peaking networks n Convenient TO-220 staggered lead package style n Standard LM240X family pinout which is designed for easy PCB layout Applications n CRT driver for color monitors with display resolutions up to 1600 x 1200 with 85 Hz refresh rate n Pixel clock frequency up to 200 MHz Schematic and Connection Diagrams DS101298-1 FIGURE 1.
