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 have found that if I shift the select signal timing relative to the input signals I start to get the correct output. I dont really understand why this should happen. Maybe you can explain why this should be.
Is this in the simulation or hardware or both?
I have not heard from you in a while. Is this still an issue for you?
I assume you have solved this issue. If not feel free to reopen this discussion at any stage.
