Monolithic Triple 9.5 ns CRT Driver
General DescriptionThe LM2439isan integrated high voltage CRT driver circuit
designedforusein color monitor applications.TheIC con-
tains three high input impedance, wide band amplifiers
which directly drivethe RGB cathodesof aCRT. Each chan-
nelhasits gain internallysetto −14andcan drive CRTca-
pacitive loadsas wellas resistive loads presentin otherap-
plications, limited onlybythe package’s power dissipation.
TheICis packagedinan industry standard 9-lead TO-220
molded plastic power package.See Thermal Considerations
section.
Features Dissipates approximately 50% less power thanthe
LM2406 Well matched with LM1279 video preamp0Vto5V input range Stable with0 pF–20pF capacitive loadsand inductive
peaking networks Convenient TO-220 staggered lead package style Standard LM243X Family Pinout whichis designedfor
easy PCB layout
Applications 1024x768 Displaysupto70Hz Refresh Pixel clock frequenciesupto75 MHz Monitors using video blanking
