Electrical characteristics

VDD = 1.8 V, T = 25 °C, unless otherwise noted.

1. Typical specifications are not guaranteed.

2. By design.

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

4. Pressure noise RMS evaluated in a controlled environment, based on the average standard deviation of 32 measurements

at highest ODR and LC_EN bit = 0, EN_LPFP = 1, LPFP_CFG = 1 for "with embedded filter (ODR/20)" and LC_EN bit = 0,

EN_LPFP = 0, LPFP_CFG = x for "without embedded filter".

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