1. Typical specifications 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. Refer to Table 20 for filter cutoff frequency.

4. Time to obtain valid data after exiting power-down mode.
