LM2412

LM2412 Monolithic Triple 2.8 ns CRT Driver December 1999 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 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 −14 and can drive CRT capacitive loads as well as resistive loads presented 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. Lower power than LM2402 with the same bandwidth Well matched with LM2202 video preamps Output swing capability: 50 VPP for VCC = 80V 1V to 5V input range 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 n n n n n 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 Features n Rise/fall times typically 2.8 ns with 8 pF load at 40 VPP Schematic and Connection Diagrams DS101298-1 DS101298-2 FIGURE 1.
