General Description

The MLX90807 and MLX90808 are fully integrated relative and absolute pressure sensors respectively. They are realized with state of the art compatible CMOS and MEMS technologies. Piezoresistors in a wheatstone bridge configuration are implanted on the edges of a silicon membrane and transform the stress induced by the pressure on the membrane into an electrical signal. An analog chain interacting with a digital core performs the conditioning of the piezoresistors electrical signal. By writing calibration settings in the chip memory an uniform transfer function is obtained over pressure and temperature

Features and Benefits
