Overview
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.
An integrated ADC converts pressure and temperature sensor readings to digitized outputs via a I2C port.
Factory calibration data is stored internally in an on-board ROM.
Utilizing the raw sensor output and calibration data, the host microcontroller executes a compensation algorithm to render Compensated Absolute Pressure with ±1 kPa accuracy.
The MPL115A2 pressure sensor’s small form factor, low power capability, precision, and digital output optimize it for barometric measurement applications.
