How does one calculate the output drift for the ADXRS646? There are 2 factors given on the datasheet, i.e. the 12deg/hr and the 0.01deg/sqrt(sec). How do these factor into the calculation? Do you sum the drift due to each?
I am sorry that this post was missed. Unfortunately, our support model for these products had substantial weaknesses when we first launched this forum. We are addressing those weaknesses right now and will respond to any future requests, much quicker in the future.
Back to this question, "drift" is a behavior, not really a metric, it is a behavior that is associated with a metric, so is is impossible to specify it so generically. The 12 deg/hour seems to relate to the In Run Bias Stability, while the 0.01 deg/sec/sqrt(Hz) number describes noise density. If this is still of interest, we would be interested in hearing more about your application, so we can help you narrow down specific metrics that might matter the most. Otherwise, we hope this went well and hope to hear from you through new discussion threads in the future. Thanks again!
