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
