*1) This is a reference value used for the internal temperature correction, and is not guaranteed to accurately output the interior temperature.

*2) The MTBF is an estimated value derived from the result of high temperature operation with a system requirement of TA=25℃

and a 60% reliability level.

*3) When the alignment is corrected by the host, the other axis sensitivity is Typ. 0.1 %.

Note) The values in the specifications are based on the data calibrated at the factory. The values may change according to the way

the product is used.

Note) The Max/Min value is the maximum/minimum value of the design or factory shipment examination, unless otherwise specified.

Note) The calibrated standard 1G gravitational acceleration value is 9.80665 m/s2
