Summary

MPL115A is a simple, high performance barometer with digital output targeting low cost commercial applications. The device employs a MEMS PRT pressure sensor with a conditioning IC to provide accurate pressure data. An integrated ADC provides digitized temperature and pressure sensor outputs via an I2C (MPL115A2) or SPI (MPL115A1) bus. Calibration data is stored in internal ROM and can be by the host MCU in a compensation algorithm that results in a Compensated Absolute Pressure with ±1 kPa accuracy over the 50 kPa to 115 kPa pressure range.
