Electrical characteristics

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

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

with LOW_NOISE_EN = 1, EN_LPFP = 1, LPFP_CFG = 1.

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

Typ. value is defined considering a 5-year life cycle of the final application.
