1 The temperature change is −40°C to +25°C or +25°C to +125°C.
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.
3 The VRE measurement is the shift in dc offset while the device is subject to 2.5 g rms random vibration from 50 Hz to 2 kHz. The DUT is configured for the ±2 g range
and an output data rate of 4 kHz. The VRE scales with the range setting.
4 When V1P8ANA and V1P8DIG are generated internally, VSUPPLY is valid. To disable the LDO and drive V1P8ANA and V1P8DIG externally, connect VSUPPLY to VSS.
5 Standby to measurement mode; valid when the output is within 1 mg of final value.
