1. The product is factory calibrated at 3.0 V. The operational power supply range is from 1.62 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. Verified at characterization level in Power Mode 1 configuration.

5. 4 mA is the maximum driving capability, ie. the maximum DC current that can be sourced/sunk by the digital pad in order to

guarantee the correct digital output voltage levels VOH and VOL.
