MPL3150A2ST1

MPL3150A2ST1 is an I²C precision pressure sensor. It is a compact, piezoresistive, absolute pressure sensor with an I²C digital interface. The pressure and temperature data is fed into a high-resolution ADC to provide fully compensated and digitized outputs for pressure in Pascals and temperature in °C. The internal processing in MPL3150A2S removes compensation and unit conversion load from the system MCU, simplifying system design. MPL3150A2S's advanced ASIC has multiple user-programmable modes such as power saving, interrupt, and autonomous data acquisition modes, including programmed acquisition cycle timing, and poll-only modes. The application includes high-accuracy barometry, smartphones, tablets, and wearable devices, GPS applications: dead reckoning, map assist, navigation, enhancement for emergency services, and weather station equipment.
