LM2429

LM2429 Monolithic Triple Channel 15 MHz DTV Driver October 2004 LM2429 Monolithic Triple Channel 15 MHz DTV Driver General Description The LM2429 is an integrated 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 −51 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 n 0V to 5V input range n Greater than 130VPP output swing capability n Stable with 0–20 pF capacitive loads and inductive peaking networks n Convenient TO-220 staggered thin lead package style Applications n AC coupled DTV applications using the 480p format as well as standard NTSC and PAL formats.
