Miniature I

C Digital Barometer
The MPL115A2 is an absolute pressure sensor with a digital I
2
C 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 I
2
C 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.
