MPL115A1ST1 is a miniature SPI digital barometer. It is an absolute pressure sensor with a digital SPI 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. It 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 SPI port. The application includes barometry (portable and desktop), altimeters, weather stations, hard disk drives, industrial equipment, health monitoring, and air control systems.
