1 / 44 page  Freescale Semiconductor Document Number: MPL3115A2 Data Sheet: Advance Information Rev 2.2, 07/2012 An Energy Efficient Solution by Freescale © 2011-2012 Freescale Semiconductor, Inc. All rights reserved. This document contains information on a new product. Specifications and information herein are subject to change without notice. I2C Precision Altimeter The MPL3115A2 employs a MEMS pressure sensor with an I2C 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 30 cm output resolution. Pressure output can be resolved with output in fractions of a Pascal, and Altitude can be resolved in fractions of a meter. The MPL3115A2 is offered in a 5 mm by 3 mm by 1.1 mm LGA package and specified for operation from -40 C to 85C. Package is surface mount with a stainless steel lid and is RoHS compliant.
