1. The product is factory calibrated at 2.5 V. The operational power supply range is from 1.71 V to 3.6 V.

2. Typical specifications are not guaranteed.

3. It is possible to remove Vdd maintaining Vdd_IO without blocking the communication busses, in this condition the

measurement chain is powered off.

4. Time to complete the entire boot sequence: from Vdd on until all configuration and calibration parameters are correctly

loaded into device registers.
