LM2421 Datasheet (National Semiconductor) - Monolithic Triple Channel HDTV Driver

LM2421, Monolithic Triple Channel HDTV Driver

The LM2421 is an integrated high voltage CRT driver circuit designed for use in HDTV applications.

The IC contains three high input impedance, wide band amplifiers which directly drive the RGB cathodes of a CRT.

Each channel has its gain internally set to *42 and can drive CRT capacitive loa
