MPL115A1
MPL115A1
Miniature SPI digital barometer, 50 to 115 kPa
Rev. 8 — 10 October 2017
Data sheet: technical data
1 General description
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.
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.
The MPL115A1 pressure sensor’s small form factor, low power capability, precision, and
digital output optimize it for barometric measurement applications.
