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. Low-noise setting disabled.

4. Low-Power Mode 1. Low-noise setting disabled.

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.
