LM2413

Monolithic Triple 4 ns CRT Driver

General Description

The LM2413 is an integrated high voltage CRT driver circuit

designed for use in high-resolution color monitor applica-

tions. 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 −14 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. See Thermal Considerations

on page 6.
