LM2459 Datasheet (National Semiconductor) - Monolithic Single Channel 15 MHz DTV CRT Driver

LM2459, Monolithic Single Channel 15 MHz DTV CRT Driver

The LM2459 is a single channel high voltage CRT driver circuit designed for use in DTV applications.

The IC contains a high input impedance, wide band amplifier which directly drives the cathode of a CRT.

The amplifier has its gain internally set to *51 and can drive CRT capacitive loads as
