Part Details:

LM2439 August 1999 Monolithic LM2439Monolithic Triple 9.5 ns CRT Driver General Description n Well matched with LM1279 video preamp n 0V to 5V input range The LM2439 is an integrated high voltage CRT driver circuit n Stable with 0 pF­20 pF capacitive loads and inductive T designed for use in color monitor applications. The IC con- peaking networks riple tains three high input impedance, wide band amplifierswhich directly drive the RGB cathodes of a CRT. Each chan- n Convenient TO-220 staggered lead package style nel has its gain internally set to -14 and can drive CRT ca- n Standard LM243X Family Pinout which is designed for pacitive loads as well as resistive loads present in other ap- easy PCB layout 9.5 plications, limited only by the package s power dissipation. The IC is packaged in an industry standard 9-lead TO-220 Applications ns molded plastic power package.
