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

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.
