LM2423
220V Monolithic Triple Channel 15 MHz CRT DTV Driver
General Description
The LM2423 is a triple channel 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 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 an industry standard 11-lead TO-220
molded plastic power package designed specifically to meet
high voltage spacing requirements. See Thermal Consider-
ations section.
