General Description
The LM2408 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 that directly drive the RGB cathodes of a CRT. The gain of each channel is internally set at -15 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.
