LM2432 Datasheet | National Semiconductor

Description The LM2432 is a single channel high voltage CRT driver circuit designed for use in Rear-Projection and Direct-View HDTV applications. The IC contains a high input impedance, wide band amplifier which can be DC coupled to a cathode of a CRT. The amplifier has its gain internally set to - 53 and can drive CRT capacitive loads as well as resistive loads present in other applications, limited only by the package’s power dissipation. .. The IC is packaged in a staggered 7-lead TO-220 molded plastic power package designed specifically to meet high voltage spacing requirements. See the section “Power Dissipation and Heatsink Calculation” for more information.
