MPL115A2

MPL115A2S Miniature I2C digital barometer, 50 kPa to 115 kPa Rev. 1.2 — 8 May 2023 Product data sheet 1 General description The MPL115A2S is an absolute pressure sensor with a digital I2C 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 environmental conditions. The MPL115A2S employs a MEMS pressure sensor with a conditioning IC to provide accurate pressure measurements from 50 kPa to 115 kPa. An integrated ADC converts pressure and temperature sensor readings to digitized outputs via a I2C port. Factory calibration data is stored internally in an onboard 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 MPL115A2S pressure sensor’s 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.
