MULTIPLEXER
The AD8063 has a disable pin used to power down the ampli-
fier to save power or to create a mux circuit. If two (or more)
AD8063 outputs are connected together, and only one is enabled,
then only the signal of the enabled amplifier will appear at the
output. This configuration is used to select from various input
signal sources. Additionally, the same input signal is applied to
different gain stages, or differently tuned filters, to make a gain-
step amplifier or a selectable frequency amplifier.
Figure 56 shows a schematic of two AD8063 devices used to
create a mux that selects between two inputs. One of these is a
1 V p-p, 3 MHz sine wave; the other is a 2 V p-p, 1 MHz sine wave.

Figure 56. Two-to-One Multiplexer Using Two AD8063s
The select signal and the output waveforms for this circuit are
shown in Figure 57. For synchronization clarity, two different
frequency synthesizers, whose time bases are locked to each
other, generate the signals.
