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.
