.. December 2005 LM2450 220V Monolithic Triple Channel 7 MHz DC Coupled CRT DTV Driver LM2450 220V Monolithic Triple Channel 7 MHz DC Coupled CRT DTV Driver General Description The LM2450 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 amplifiers 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. Normally 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...
