3. Noise density is the same for all ODRs. Low-noise setting enabled.

4. RMS noise is the same for all ODRs. Low-noise setting disabled.

5. Max. values from design and characterization at ambient temperature (T = 25°C).

6. Values after factory calibration test and trimming at T = 25 °C.

7. Based on characterization data on a limited number of samples. Not measured during final test for

production.

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 enabled.

4. Typical value of current consumption measured at T = 25 °C.

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

6. 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.
