产品概述
描述
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 to provide fully compensated and digitized outputs for pressure in Pascals and temperature in °C. The compensated pressure output can then be converted to altitude.The internal processing in MPL3115A2S removes compensation and unit conversion load from the system MCU, simplifying system design.
The MPL3115A2S 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. Typical active supply current is 40 μA per measurement-second for a stable 10 cm output resolution.
