1.

The product is factory calibrated at 2.5 V. The operational power supply range is from 2.16 V to 3.6 V.

2.

Typical specification 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.
