Texas Instruments LM2432
The LM2432 is a single channel high voltage CRT driver circuit designed for use in Rear-Projection and DirectView 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.| Part No. | LM2432 |
