Overview
LM2432 220V Monolithic Single Channel 37 MHz HDTV CRT Driver April 2005 LM2432 220V Monolithic Single Channel 37 MHz HDTV CRT Driver General 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.
