... Switching in LCD and Plasma Displays Video Switchers and Routers PRODUCT DESCRIPTION The AD8180 (single) and AD8182 (dual) are high speed 2-to-1 multiplexers. They offer –3 dB signal bandwidth greater than 750 MHz along with slew rate of 750 V/ s. With better than crosstalk and isolation, they are useful in many high speed applications ...

... Typically one source would be the PC’s normal output, the second source might be a specialized source such as MPEG video. Figure 23 shows how such a circuit could be realized using the AD8180 and AD8182 and three current feedback op amps. The video inputs to the multiplexers are terminated with 75 resistors ...

... AD8182 to create a 4-to-1 multiplexer. The enable control pins on the multiplexers allow the outputs to be wired directly together. Because of its high bandwidth, the AD8182 is capable of driv- ing the switched capacitor input stage of the AD876 without additional buffering. In addition to having the required the bandwidth necessary to consider the settling time of the multiplexer ...

... Ordering Guide. Because the footprint of the AD8180 fits directly on to that of the AD8182, one board layout can be used for both devices. In the case of the AD8180, only the top half of the board is populated. Figure 28 shows the silkscreen of the component side and Fig- ure 30 shows the silkscreen of the solder side ...
