Miniature SPI Digital Barometer
The MPL115A1 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 1 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.
MPL115A1 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 a SPI port. Calibration Data
is stored in internal ROM. Utilizing raw sensor output, the host microcontroller
executes a compensation algorithm to render Compensated Absolute Pressure
with 1 kPa accuracy.
The MPL115A1 pressure sensor’s small form factor, low power capability,
precision, and digital output optimize it for barometric measurement applications.

... Temp Sensor Sensor Figure 1. Uncompensated Pressure Sensor Schematic Compensation The pressure compensation for MPL115A1 is based on a 2-dimensional, second order polynomial based on Microsystems mst_trimlib library. The 10-bit compensated pressure output, Pcomp, is calculated as follows: Pcomp = a0 + (b1 + c11*Padc + c12*Tadc) * Padc + (b2 + c22*Tadc) * Tadc Where: Padc is the 10-bit pressure output of the MPL115A1 ADC, ...
