1. Typical specifications are not guaranteed.

2. By design, the typ. value is defined based on characterization data with 10 hPa pressure interval in mode 1 and 100 hPa

pressure interval in mode 2.

3. Pressure noise RMS evaluated in a controlled environment, based on the average standard deviation of 50 measurements

with AVG = 512, BW = ODR/9.

4. Output data rate is configured acting on ODR[3:0] in CTRL_REG1 (10h).
