The MPL015A2 is an absolute pressure sensor with digital output for low cost
applications. A miniature 5 x 3 x 1.2 mm LGA package ideally suits it for portable
electronics and space constrained applications. Low current consumptions of
5 μA during Active mode and 0.06 μA during Shutdown (Sleep) mode target
battery and other low-power applications. A wide operating temperature range
from -40°C to +105°C fits demanding environmental requirements.
MPL015A2 employs a MEMS pressure sensor with a conditioning IC to provide
accurate pressure measurement from 50 to 115 kPa. An integrated ADC provides
digitized temperature and pressure sensor outputs via an I
2
C port. Calibration
Data is stored in internal ROM. Utilizing raw sensor output, the host
microcontroller executes a compensation algorithm to render Compensated
Absolute Pressure.
The MPL015A2 pressure sensor’s small form factor, low power capability,
precision, and digital output optimize it for barometric measurement applications.
