We have a strange situation where it appears that some ADXL320 devices are mechanically stuck in a state.
The parts worked perfectly during final product test. Units were shipped to a customer, and on their incoming inspection, units failed.
No alarm detected when the unit is moved. Faulty units were returned to us. We confirmed they were faulty.
Then we found that after a slight tap with a small hammer, the ADXL320 started working again - hence our conclusion that the MEMs was mechanically stuck / jammed somehow.
Has this been noted by anyone else?
