Part Details:

LM2468 December 2000 Monolothic LM2468Monolothic Triple 14nS High Gain CRT Driver General Description n 0V to 3.75V input range n Stable with 0-20pF capacitive loads and inductive The LM2468 is an integrated high voltage CRT driver circuit peaking networks designed for use in color monitor applications. The IC con- T tains three high input impedance wide band amplifiers, n Matched to the LM126X series preamplifier and riple LM2479/2480 bias clamp which directly drive the RGB cathodes of a CRT. Eachchannel has its gain internally set to -20 and can drive CRT n Maintains standard LM243X Family Pinout which is capacitive loads as well as resistive loads present in other designed for easy PCB layout 14nS applications, limited only by the package s power dissipation. n Convenient TO-220 staggered 9 lead package style The IC is packaged in an industry standard 9 lead TO-220molded plastic package. Applicationsn Up to 1024 X 768 at 60 Hz (or 800 X 600 at 72/75 Hz) High Features n Pixel clock frequencies up to 50 MHz n Higher gain to accommodate CMOS preamplifiers n Monitors using video blanking Gain Schematic Diagram Connection Diagram CRT Driver DS200135-2 Note: Tab is at GND.
