LM2465 Datasheet | National Semiconductor

Description The LM2465 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 9-lead TO-220 molded plastic package. Features n Higher gain to match LM126X CMOS preamplifiers n 0V to 3.75V input range n Stable with 0- 20 p F capacitive loads and inductive peaking networks n Same pinout as LM2467/8/9, maintaining the standard LM243X Family pinout for easy PCB layout n Convenient TO-220 staggered lead package style Applications n Up to 1280 x 1024 at 75Hz n Pixel clock frequencies up to 135 MHz n Monitors using video blanking Schematic and Connection Diagrams DS200190-2 Note: Tab is at GND Top View Order Number LM2465TA DS200190-1 FIGURE 1.
