1 / 12 page  LM2451 220V Monolithic Triple Channel 12 MHz DC Coupled CRT DTV Driver General Description The LM2451 is a triple channel high voltage DC coupled CRT driver circuit designed for use in DTV applications. The IC contains three high input impedance, wide band amplifi- ers which directly drive the RGB cathodes of a CRT. Each amplifier has a summing input where the DC level of the output is controlled by a low voltage DC input voltage. Nor- mally the DC input voltage is from a DAC. Each channel has its gain internally set to −54 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 a 15-lead TO-247 molded plastic power package designed specifically to meet high voltage spacing requirements. See Thermal Considerations section. Features n 12 MHz bandwidth at 130V P-P n 100V black level adjustment range using 0V to 5V input n Current output for IK feedback systems n Greater than 130V P-P output swing capability n 0V to 5V input voltage range n Stable with 0 pF–20 pF capacitive loads and inductive peaking networks n Convenient TO-247 staggered thin lead package style Applications n DC coupled DTV applications using the 480p format as well as standard NTSC and PAL formats.
