Integrated pressure sensor 15 to 115 kPa (2.2 to 16.7 psi), 0.2 to 4.8 V output.
The MPX4115A series is designed to sense absolute air pressure in altimeter or barometer (BAP) applications. Freescale's BAP sensor integrates on-chip, bipolar op amp circuitry and thin film resistor networks to provide a high level analog output signal and temperature compensation.
Recommended power supply decoupling is given in the data sheet:
The output voltage is a linear function of the pressure and does not need any compensation for errors within the 0° - 85° C temperature range. The error correction outside this range is given in the data sheet.
