LM2403

Monolithic Triple 4.5 nS CRT Driver

General Description

The LM2403 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 pre-

sented by 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 5.
