LM2433 Monolithic Single Channel 16 MHz EDTV CRT Driver

The LM2433 is a single channel high voltage CRT driver circuit designed for use in Rear-Projection and Direct-View EDTV 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 .
