Freescale Semiconductor Data Sheet: Technical Data Document Number: MPL115A2 Rev. 9, 02/2013 Miniature I2C Digital Barometer The MPL115A2 is an absolute pressure sensor with a digital I2C output targeting low cost applications. A miniature 5 x 3 x 1.2 mm LGA package is ideally suited for the space constrained requirements of portable electronic devices. Low current consumptions of 5 μA during Active mode and 1 μA during Shutdown (Sleep) mode are essential when focusing on low-power applications. The wide operating temperature range spans from -40°C to +105°C to fit demanding environmental conditions. The MPL115A2 employs a MEMS pressure sensor with a conditioning IC to provide accurate pressure measurements from 50 to 115 kPa.
