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 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 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.
