Miniature SPI Digital Barometer

MPL115A1

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.

50 to 115 kPa

The MPL115A1 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 SPI 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.

LGA Package

5.0 mm x 3.0 mm x 1.2 mm

The MPL115A1 pressure sensor’s small form factor, low power capability,

precision, and digital output optimize it for barometric measurement

applications.
