AD810
2:1 VIDEO MULTIPLEXER
The outputs of two AD810s can be wired together to form a
2:1 mux without degrading the flatness of the gain response.
Figure 54 shows a recommended configuration which results in
–0.1 dB bandwidth of 20 MHz and OFF channel isolation of
77 dB at 10 MHz on 5 V supplies. The time to switch between
channels is about 0.75 s when the disable pins are driven by
open drain output logic. Adding pull-up resistors to the logic
outputs or using complementary output logic (such as the
74HC04) reduces the switching time to about 180 ns. The
switching time is only slightly affected by the signal level.
