2:1 Video Multiplexer
Configuring two amplifiers as unity gain followers and using the
third to set the gain results in a high performance 2:1 mux
(Figures 39 and 40). This circuit takes advantage of the very low
crosstalk between Channels 2 and 3 to achieve the OFF channel
isolation shown in Figure 40. This circuit can achieve
differential gain and phase of 0.03% and 0.07 respectively.

The AD8013 can be used to build a circuit for switching between
any two arbitrary gains while maintaining a constant input
impedance. The example of Figure 41 shows a circuit for switching
between a noninverting gain of 1 and an inverting gain of 1. The
total time for channel switching and output voltage settling is
about 80 ns.
