I2C precision pressure sensor

Caution

msc896

This device is sensitive to ElectroStatic Discharge (ESD). Observe precautions for handling electrostatic

sensitive devices.

Such precautions are described in the ANSI/ESD S20.20, IEC/ST 61340-5, JESD625-A, or equivalent

standards.

[1]

Oversample (OSR) modes internally combine and average samples to reduce noise.

[2]

Pressure offset drift of ±20 Pa from 0 s to 120 s from 25 °C to 40 °C. Verified by characterization.

[3]

Reference pressure = 101.325 kPa (sea level).
