Description

The LM2439 is an integrated high voltage CRT driver circuit esigned for use in color monitor applications. The IC contains hree high input impedance, wide band amplifiers
which directly drive the RGB cathodes of a CRT. Each channel as its gain internally set to −14 and can drive CRT capacitive oads as well as resistive loads present in other applications, imited only by the package's power dissipation.

The LM2439 is packaged in an industry standard 9-lead TO-220 olded plastic power package. See Thermal Considerations ection
