Dear team,


I would like to ask about ODR accuracy of MMA8451Q.

My customer has a doubt on the accuracy of ODR(+-2%) from their test.

The customer’s test is as below.

  1. Set up the ODR=100Hz by register.
  2. Set up the interruption from MMA8451Q when FIFO contains 16 data.
  3. MMA8451Q will issue the interruption with 160mS period.

As a result, they saw the interruption period from MMA8451Q could exceed from +-2%.

Is their test procedure is correct for ODR accuracy measurement?

Could you show me how to measure the ODR accuracy?


Best Regards,
