LM2405 Datasheet | National Semiconductor

Description The LM2405 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 at - 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 IC is packaged in an industry standard 11 lead TO-220 molded plastic power package. See thermal considerations on page 5. n Output swing capability: 50 VPP for VCC = 80 40 VPP for VCC = 70 30 VPP for VCC = 60 n Pinout designed for easy PCB layout n 0V to 6V input range n Stable with 0 p F- 20 p F capactive loads n Convenient TO-220 staggered lead package style Applications n CRT driver for 1280 x 1024 (Non-interlaced) and XGA display resolution color monitors n Pixel clock frequency up to 130 MHz n Monitors using video blanking Features n Rise/fall times typically 7 ns with 8 p F load Schematic and Connection Diagram DS012682-2 Tab is at GND Top View Order Number LM2405T DS012682-1 FIGURE 1.
