LM2421 Monolithic Triple Channel HDTV Driver November 2001 LM2421 Monolithic Triple Channel HDTV Driver General Description The LM2421 is an integrated high voltage CRT driver circuit designed for use in HDTV 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 −42 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. See Thermal Considerations section.
