Miniature SPI Digital Barometer

The MPL115A1 is an absolute pressure sensor with a digital SPI 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 environment conditions.
