LM2422 Datasheet | National Semiconductor

Description The LM2422 is a triple channel high voltage CRT driver circuit designed for use in DTV applications. The IC contains three high input impedance, wide band amplifiers which directly drive the RGB cathodes of a CRT. Each channel has its gain internally set to - 52 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 11-lead TO-220 molded plastic power package designed specifically to meet high voltage spacing requirements. See Thermal Considerations section. Features 30 MHz bandwidth Greater than 130VP-P output swing capability 0V to 5V input voltage range Stable with 0 p F- 20 p F capacitive loads and inductive peaking networks n Convenient TO-220 staggered thin lead package style n n n n Applications n HDTV applications using the 1080i format as well as other DTV and standard TV formats.
