DESCRIPTION

· The MPL3115A2 is a compact piezoresistive absolute pressure sensor with an I2C digital interface.

· It operates within a range of 20 kPa to 110 kPa, covering all surface elevations on Earth.

· The sensor features an on-chip temperature sensor for temperature compensation.

· It provides fully compensated and digitized outputs for pressure in Pascals and temperature in °C.

· The internal processing offloads compensation and unit conversion from the system MCU.

· It supports multiple user-programmable modes including power saving, interrupt, and autonomous data acquisition.

FEATURES

· Operating range: 20 kPa to 110 kPa absolute pressure.

· Calibrated range: 50 kPa to 110 kPa absolute pressure.

· Calibrated temperature output: −40 °C to 85 °C.

· I2C digital output interface (up to 400 kHz).

· Precision ADC with 0.1 meter effective resolution.

· Direct reading for pressure (20-bit), altitude (20-bit), and temperature (12-bit).

· Programmable interrupts and autonomous data acquisition with a 32-sample FIFO.

· Supply voltage: 1.95 V to 3.6 V, internally regulated.

· Operating temperature: −40 °C to +85 °C.

APPLICATIONS

· Altitude measurement and tracking.

· Weather stations and environmental monitoring.

· Indoor navigation and location-based services.

· Drones and UAVs for altitude control.

· Wearable devices for fitness and health monitoring.
