MPL115A2

Miniature I²C digital barometer, 50 to 115 kPa

Rev. 10 — 10 October 2017

Data sheet: technical data

1 General description

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.
