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.
