Part Details:

LM2438 August 1999 Monolithic LM2438Monolithic Triple 13.5 ns CRT Driver General Description Features The LM2438 is an integrated high voltage CRT driver circuit n Well matched with LM1279 video preamp T designed for use in color monitor applications. The IC con- n 0V to 5V input range riple tains three high input impedance, wide band amplifiers n Stable with 0­20 pF capacitive loads and inductive which directly drive the RGB cathodes of a CRT. Each chan- peaking networks nel has its gain internally set to -14 and can drive CRT ca- n Convenient TO-220 staggered lead package style pacitive loads as well as resistive loads present in other ap- 13.5 n Standard LM243X Family Pinout which is designed for plications, limited only by the package s power dissipation. easy PCB layout The IC is packaged in an industry standard 9-lead TO-220molded plastic power package.
