1. Typical specifications are not guaranteed.

2. OPC: One-Point Calibration, see RPDS_L (18h), RPDS_H (19h).

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

at highest ODR and with LC_EN bit = 0, EN_LPFP = 1, LPFP_CFG = 1.

4. Output data rate is configured acting on ODR[2:0] in CTRL_REG1 (10h).
