REV. A
N:1 MULTIPLEXER
A multiplexer of arbitrary size can be formed by combining the
desired number of AD810s together with the appropriate
selection logic. The schematic in Figure 58 shows a
recommendation for a 4:1 mux which may be useful for driving
a high impedance such as the input to a video A/D converter
(such as the AD773). The output series resistors effectively
compensate for the combined output capacitance of the OFF
channels plus the input capacitance of the A/D while
maintaining wide bandwidth. In the case illustrated, the –0.1 dB
bandwidth is about 20 MHz with no peaking. Switching time
and OFF channel isolation (for the 4:1 mux) are about 250 ns
and 60 dB at 10 MHz, respectively.
