MLX90807/90808
Integrated Relative and Absolute Pressure Sensors
1 Functional Diagram
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
