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 A during Active mode and 1 A 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 sensors small form factor, low power capability, precision, and digital output optimize it for barometric measurement applications. 2 Features Digitized pressure and temperature information together with programmed calibration coefficients for host micro use.
