3 Bias repeatability is the RSS combination of the following sources of bias drift: turn-on drift, thermal hysteresis, temperature cycling (1000 cycles, −40°C to +105°C) and

high temperature operating life (1000 hours, +105°C).

4 Bias error over temperature indicates bias variation from the 25°C reference.

5 Specified for 10 Hz to 40 Hz, at a nominal fSM sample rate, and no digital filtering.

1 Sensitivity repeatability is the RSS combination of the following sources of bias drift: thermal hysteresis, temperature cycling (1000 cycles, −40°C to +105°C), and high

temperature operating life (1000 hours, +105°C).

2 This measurement is based on the deviation from a best fit linear model.

3 Bias repeatability is the RSS combination of the following sources of bias drift: turn-on drift, thermal hysteresis, temperature cycling (1000 cycles, −40°C to +105°C) and

high temperature operating life (1000 hours, +105°C).

4 Bias error over temperature indicates bias variation from the 25°C reference.

5 Noise density specified for 10 Hz to 40 Hz, at a nominal fSM sample rate, and no digital filtering.
