I have a customer using a ADXL312W. According to the datasheet, the typical 0g offset temperature coefficient is +-0.8mg/C for x/y. The typical characteristics on page 7 do not match this. The median temperature coefficient is -0.8mg, but the typical characteristics are between -2mg and 0.3mg, so I have a couple questions:
1) What value should be trusted?
2) Are the typical values expected to change between batches? If so, is it possible to get a test report for the particular batch?
