220V Monolithic Triple Channel 10 MHz CRT DTV Driver
LM2425
220V Monolithic Triple Channel 10 MHz CRT DTV Driver
General DescriptionThe LM2425isa triple channel high voltage CRT driver
circuit designedfor usein DTV applications. TheIC contains
three high input impedance, wide band amplifiers which
directly drivethe RGB cathodesofa CRT. Each channel has
its gain internally setto −53 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 designed specificallyto meet
high voltage spacing requirements. See Thermal Consider-
ations section.
Features10 MHz bandwidthat 130VPP output swing Upto 170VPP output swing withAC couplingto
cathodes0Vto5V input voltage range Stable with0 pF–20pF capacitive loads and inductive
peaking networks Convenient TO-220 staggered thin lead package style
Applications ACor DC coupled DTV applications.
