The axis of rotation must be perpendicular to the earth’s gravity to maintain the factory-calibrated accuracy of the sensor. 2 Guaranteed by design. 3 Endurance is qualified as per JEDEC Standard 22 Method A117 and measured at −40°C, +25°C, +85°C, and +125°C. 4 Retention lifetime equivalent at junction temperature (TJ) 55°C as per JEDEC Standard 22 Method A117. Retention lifetime decreases with junction temperature. Rev.
