1 Characterized but not 100% tested.
2 Repeatability is predicted for a 10 year life and includes shifts due to the HTOL (TA = 150°C, VSUPPLY = 3.6 V, and 1000 hours), temperature cycling (−55°C to +125°C and
1000 cycles), velocity random walk, broadband noise, and temperature hysteresis. Repeatability in relation to time follows the square root law. For example, to obtain
offset repeatability of the x-axis for 2.5 years, use the following equation: ±4.25 mg × √(2.5 years/10 years) = ±2.125 mg.
3 The temperature change is −40°C to +25°C or +25°C to +125°C.
4 The VRE measurement is the shift in dc offset while the device is subject to 7.5 g rms random vibration from 50 Hz to 2 kHz. The DUT is configured for the ±10 g range
and an output data rate of 4 kHz. The VRE scales with the range setting.
5 Based on characterization.
6 ±10 g indicates a test condition. The self test result converted to the acceleration value is independent of the selected range.
7 When V1P8ANA and V1P8DIG are generated internally, VSUPPLY is valid. To disable the LDO regulator and drive V1P8ANA and V1P8DIG externally, connect VSUPPLY to VSS.
8 Standby to measurement mode. This specification is valid when the output is within 1 mg of final value.
