My customer use  AD8339 in their CW (Continuous wave) Board of their ultrasound equipment.

And they use 3~6ea of AD8339 in a their CW board


However, they say that they have a problem in CW mode  during their production qualification test.

One AD8339 among 3~6ea of AD8339 has a strange wave pattern and this problem is occurred at randomic location among 3 ~6 ea of AD8339 locations.

(Unfortunately, they can't capture a wave pattern. They only confirm the output of monitor in their equipment operating their SW.)

FAR is ongoing , but before FAR, I want to get your opinions about their schematic around AD8339.


Would you confirm attached schematic of AD8339?


Please review their schematic and let me know your opinions ASAP.


If you have any questions, please let me know.
