MPL115A2ST1

MPL115A2ST1 is a miniature I²C digital barometer. The absolute pressure sensor with a digital I²C output targeting low-cost applications. A miniature 5 x 3 x 1.2mm LGA package is ideally suited for the space-constrained requirements of portable electronic devices. Low current consumptions of 5µA during active mode and 1µA 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. An integrated ADC converts pressure and temperature sensor readings to digitized outputs via an I²C port. The application includes barometry (portable and desktop), altimeters, weather stations, hard-disk drives (HDD), industrial equipment, health monitoring, and air control systems.
