Part Details:

LM1205A/LM1207A August 1996 LM1205A/LM1207A130 MHz/85 MHz RGB Video Amplifier System withBlanking General Description n ESD susceptibility above 3 kV 130 n Three externally gated single ended input comparators The LM1205A/LM1207A is a very high frequency video am- for cutoff and brightness control plifier system intended for use in high resolution RGB moni- MHz/85 tor applications. In addition to the three matched video am- n 0V to 4V, high input impedance DC contrast control (>40 dB range) plifiers, the LM1205A/LM1207A contains three gated singleended input black level clamp comparators for brightness n 0V to 4V, high input impedance DC drive control for control, three matched DC controlled attenuators for contrast each video amplifier (-6 dB to 0 dB range) control, and three DC controlled sub-contrast attenuators n Spot killer, blanks output when V < 10.6V CC providing gain trim capability for white balance. All DC con- n Capable of 7 V output swing (slight reduction in PP MHz trol inputs offer high input impedance and an operation bandwidth) range from 0V to 4V for easy interface to bus controlled n Output stage blanking alignment systems. The LM1205A/LM1207A also contains a n Output stage directly drives most hybrid or discrete CRT RGB blanking circuit which clamps the video output voltage during drivers blanking to within 0.1V above ground. This feature providesblanking capability at the cathodes of the CRT. A spot killer is Applications provided for CRT phosphor protection during power-down.
