In my prototype board, where there are a lot of ADG5412BF devices, in the D2 (or S1, the switch 1 is closed) pins there is an oscillation of about 48/49 MHz of frequency and 50 mVpp. Is possible that the devices produce itself this oscillation? The power supplies (+ - 7.3 V) are free from this oscillation.
Thank you Regards Davide Badoni
The device itself should not produce this oscillation. Can you confirm what pins you see the voltage on?
Thank you David!
The pins are n. 2 and n. 3.
Can you test the ADG5412BF while isolating the rest of your set up to see if the oscillation still occurs?
I have not heard from you in a while. Is this still an issue?
