1 / 14 page LM2470 Monolithic Triple 7.0 ns CRT Driver General Description The LM2470 is an integrated high voltage CRT driver circuit designed for use in color monitor applications. The IC con- tains three high input impedance, wide band amplifiers which directly drive the RGB cathodes of a CRT. Each channel has its gain internally set to −27 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 power package. See the Thermal Consider- ations section for more information. Features n Well matched to the LM1236/46 CMOS preamplifiers n Swing up to 60 PP (15V - 75V) 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 LM246X Family pinout which is designed for easy PCB layout Applications n 1024 x 768 displays up to 85 Hz refresh n Pixel clock frequencies up to 95 MHz n Monitors using video blanking Schematic Diagram 20087101 FIGURE 1.
