Freescale Semiconductor Document Number: MPL3115A2 Data Sheet:Technical Data Rev 3.0, 12/2013 An Energy Efficient Solution by Freescale 2 Xtrinsic MPL3115A2 I C Precision MPL3115A2 Altimeter 50 to 110 kPa 2 The Xtrinsic MPL3115A2 employs a MEMS pressure sensor with an I C interface to provide accurate Pressure/Altitude and Temperature data. The sensor outputs are digitized by a high resolution 24-bit ADC. Internal processing removes compensation tasks from the host MCU system. Multiple user- programmable, power saving, interrupt and autonomous data acquisition modes are available, including programmed acquisition cycle timing, and poll-only modes. Typical active supply current is 40 A per measurement-second for a stable 10 cm output resolution. The MPL3115A2 is offered in a 5 mm x 3 mm x 1.1 mm LGA package and specified for operation from -40 C to 85 C. Package is surface mount with a stainless steel lid and is RoHS compliant.
