1. The product is factory calibrated at 1.8 V. The operational power supply range is from 1.62 V to 1.98 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. 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.
