Right now, I have 3 setups that have 3 172s each, so 9 in total. Using the same 2 accelerometers I cycled them through the 3 different stack up. I noticed that the DC offset would always change as the stack up changed. Then just to be thorough I cycled through with a different accelerometer pair through each of the 3 stack ups. When doing this the DC offset remained the same from HW stack up to stack up. Basically, the new accelerometer pair didn’t change the DC offset that I had measured before.
What about when the DC offset is out of spec of the datasheet value of 5.1mV? I had two measurements where the offset was measured at -6mV and -8.75mV as shown in the last image.
