LM2421
Monolithic Triple Channel HDTV Driver
General DescriptionThe LM2421isan integrated high voltage CRT driver circuit
designedfor usein HDTV applications. TheIC contains
three high input impedance, wide band amplifiers which
directly drivethe RGB cathodesofa CRT. Each channel has
its gain internally setto −42 and can drive CRT capacitive
loadsas wellas resistive loads presentin other applications,
limited onlybythe package’s power dissipation.
TheICis packagedinan industry standard 11-lead TO-220
molded plastic power package. See Thermal Considerations
section.
Features0Vto5V input range Stable with 0–20pF capacitive loads and inductive
peaking networks Convenient TO-220 staggered lead package style Maintains standard LM240X Family pinout whichis
designedfor easy PCB layout
Applications AC coupled HDTV applications using the 1080i and
720p formatsas wellas standard NTSC and PAL
formats.
