I am using the ADG719 switch. I have two inputs with a frequency of 125kHz. I am switching between the two using a logic signal of 250kHz. But when I look at the output of the switch I just see a pulse of one of the signals then about a gap of 12ms then a pulse again. Its as though the switch is only letting through one of the signals every so often. Anyone have any idea why this would be?
I assume you have solved this issue. If not feel free to reopen this discussion at any stage.
Hi David. Here is the schematic.
Here is one of the inputs
This is the output. If I zoom out then I get a pulse about every 12ms, as though its only letting a channel through at that rate.
This is the select signal
