MPL3115A2S - NXP

MPL3115A2S I2C precision pressure sensor

The MPL3115A2S is a compact, piezoresistive, absolute pressure sensor with an I2C digital interface. MPL3115A2S has a wide operating range of 20 kPa to 110 kPa, a range that covers all surface elevations on earth. The MEMS is temperature compensated utilizing an on-chip temperature sensor. The pressure and temperature data is fed into a high-resolution ADC t.
