Description

The LM2445 is an integrated high voltage CRT driver circuit designed for use in color monitor 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 -20 and can drive CRT capacitive loads as well as resistive loads present in other applications, limited only by the package's power dissipation.

The LM2445 is packaged in an industry standard 9-lead TO-220 molded plastic power package. See the Thermal Considerations section for more information.
