LM2457 Monolithic Triple 7.5nS CRT Driver With Integrated Clamp and G1 Blanking
LM2457 Monolithic Triple 7.5nS CRT Driver With Integrated Clamp and G1 Blanking
General Description
The LM2457 driver is an integrated high voltage triple CRT driver circuit designed for use in color monitor applications. The input signal interface to the IC is a multiplexed signal containing both clamp and video signal information, relative to an external 1.7 VDC reference. The IC contains three high gain, differential input, high input impedance, wide band amplifiers which directly drive the RGB cathodes of a CRT. Each channel has its gain internally set to -52 and can drive...
