1 / 18 page TLH11440 December 1995 LM1202 230 MHz Video Amplifier System General Description The LM1202 is a very high frequency video amplifier system intended for use in high resolution monochrome or RGB color monitor applications In addition to the wideband video amplifier the LM1202 contains a gated differential input black level clamp comparator for brightness control a DC controlled attenuator for contrast control and a DC con- trolled sub contrast attenuator for drive control The DC control for the contrast attenuator is pinned out separately to provide a more accurate control system for RGB color monitor applications All DC controls offer a high input im- pedance and operate over a 0V to 4V range for easy inter- face to bus controlled alignment systems The LM1202 op- erates from a nominal 12V supply but can be operated with supply voltages down to 8V for applications that require re- duced IC package power dissipation characteristics Features Y Wideband video amplifier (fb3dB e 230 MHz at VO e 4VPP) Y tr tf e 15 ns at VO e 4VPP Y Externally gated comparator for brightness control Y 0V to 4V high input impedance DC contrast control (l40 dB range) Y 0V to 4V high input impedance DC drive control (g3 dB range) Y Easy to parallel three LM1202s for optimum color track- ing in RGB systems Y Output stage clamps to 065V and provides up to 9V output voltage swing Y Output stage directly drives most hybrid or discrete CRT amplifier stages Applications High resolution CRT monitors Video switches Video AGC amplifier Wideband amplifier with gain and DC offset control Block and Connection Diagram TLH11440 – 1 Order Number LM1202N or LM1202M See NS Package Number N20A or M20B C1996 National Semiconductor Corporation RRD-B30M66Printed in U S A |
