LM2403  Product Folder

The LM2403 is an integrated high voltage CRT driver circuit designed for use in high resolution 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 -14 and can drive CRT capacitive loads as well as resistive loads presented 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.
