LM2460

Monolithic Triple Channel High Swing CRT Driver

General Description

The LM2460 is an integrated high voltage CRT driver circuit

designed for use in high brightness monitor applications. The

IC contains three high input impedance, wide band amplifi-

ers which directly drive the RGB cathodes of a CRT. Each

channel has its gain internally set to −30 and can drive CRT

capacitive loads as well as resistive loads present in other

application, limited only by the package’s power dissipation.

The IC is packaged in an industry standard 9 lead TO-220

molded plastic package.
