LM1207N
The LM1205/LM1207 is a very high frequency video amplifier system intended for use in high resolution RGB monitor applications. In addition to the three matched video amplifiers, the LM1205/LM1207 contains three gated single ended input black level clamp comparators for brightness control, three matched DC controlled attenuators for contrast control, and three DC controlled sub-contrast attenuators providing gain trim capability for white balance. All DC control inputs offer high input impedance and an operation range from 0V to 4V for easy interface to bus controlled alignment systems. The LM1205/LM1207 also contains a blanking circuit which clamps the video output voltage during blanking to within 0.1V above ground. This feature provides blanking capability at the cathodes of the CRT. A spot killer is provided for CRT phosphor protection during powerdown.
