LM2463

LM2463 Monolithic Triple 4 ns CRT Driver February 2001 LM2463 Monolithic Triple 4 ns CRT Driver General Description The LM2463 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 11-lead TO-220 molded plastic power package. See Thermal Considerations section. Features n Higher gain to match LM126X CMOS preamplifiers n 0V to 3.75V input range n Stable with 0–20 pF capacitive loads and inductive peaking networks n Convenient TO-220 staggered lead package style n Maintains standard LM240X Family pinout which is designed for easy PCB layout Applications n 1600 x 1200 displays up to 70Hz refresh n Pixel clock frequencies up to 180 MHz n Monitors using video blanking Schematic and Connection Diagrams DS200128-2 Note: Tab is at GND Top View Order Number LM2463TA DS200128-1 FIGURE 1.
