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.
