The MLX90808 is an integrated absolute pressure sensor realised in CMOS technology. It consists of an analog signal chain that interacts with the digital core and on-chip temperature sensor in order to provide uniform overall sensing characteristics after calibration and to cancel the temperature related parameter drifts. The output is proportional to the applied pressure with an adjustable slope and offset. The chip is ratiometric and goes rail-to-rail with a 1mA source and sink capability.
