1. Typical specification are not guaranteed.
2. It is possible to remove Vdd maintaining Vdd_IO without blocking the communication busses, in this condition the
measurement chain is powered off.
3. Referred to Table 25 for the ODR value and configuration.
4. Time to obtain valid data after exiting power-down mode.
b. The product is factory calibrated at 2.5 V.
c. The product is factory calibrated at 2.5 V. The operational power supply range is from 1.71 V to 3.6 V.
