Part Details:

LM1205 October 1993 130 LM1205 MHz 130 MHz RGB Video Amplifier System with Blanking General Description Y Three externally gated single ended input comparatorsfor cutoff and brightness control RGB The LM1205 is a very high frequency video amplifier system Y Provisions for individual gain control (Drive) of each intended for use in high resolution RGB monitor applica- video amplifier tions In addition to the three matched video amplifiers the Y 0V to 4V high input impedance DC contrast control LM1205 contains three gated single ended input black level (l40 dB range) Video clamp comparators for brightness control three matched Y DC controlled attenuators for contrast control and three DC 0V to 4V high input impedance DC drive control controlled sub-contrast attenuators providing gain trim ca- (g3 dB range) pability for white balance All DC control inputs offer high Y Capable of 7 VPP output swing (slight reduction in input impedance and an operation range from 0V to 4V for bandwidth) Amplifier easy interface to bus controlled alignment systems The Y Output stage blanking LM1205 also contains a blanking circuit which clamps the Y Output stage directly drives most hybrid or discrete video output voltage during blanking to within 0 1V of CRT drivers ground This feature provides blanking capability at thecathode of the CRT ApplicationsY High resolution RGB CRT monitors Features Y System Video AGC amplifiers Y Three wideband video amplifiers 130 MHz b3 dB Y Wideband amplifiers with gain and DC offset controls (4 VPP output)
