Miniature I²C Digital Barometer

The MPL115A2 is an absolute pressure sensor with digital output for low cost

applications. A miniature 5 x 3 x 1.2 mm LGA package ideally suits it for portable

electronics and space constrained applications. Low current consumptions of

5 μA during Active mode and 1 μA during Shutdown (Sleep) mode target battery

and other low-power applications. A wide operating temperature range from -40°C

to +105°C fits demanding environmental requirements.

MPL115A2

50 to 115 kPa

Application Examples

• Barometry (portable and desk-top)

• Altimeters

MPL115A2 employs a MEMS pressure sensor with a conditioning IC to provide

accurate pressure measurement from 50 to 115 kPa. An integrated ADC provides

digitized temperature and pressure sensor outputs via an I²C port. Calibration

Data is stored in internal ROM. Utilizing raw sensor output, the host

microcontroller executes a compensation algorithm to render Compensated

Absolute Pressure with 1 kPa accuracy.

• Weather Stations

• Hard Disk-Drives (HDD)

• Industrial Equipment

• Health Monitoring

The MPL115A2 pressure sensor’s small form factor, low power capability,

precision, and digital output optimize it for barometric measurement applications.

• Air Control Systems

Features

• Digitized pressure and temperature information together with programmed

calibration coefficients for host micro use.

• Factory Calibrated

• 50 kPa to 115 kPa Absolute Pressure

• 1 kPa Accuracy

• 2.375 V to 5.5 V Supply

• Integrated ADC

• I²C Interface

• Monotonic Pressure and Temperature Data Outputs

• Surface Mount RoHS Compliant Package
