DESCRIPTION
The SM1111-EEN-S-115-001 is an absolute pressure sensor for barometric air pressure measurement (BAP). It includes a piezoresistive pressure sensor die and a signal processing IC, which performs amplification and thermal compensation of the pressure sensor output to provide a linear, thermally stable signal output.
The sensor delivers calibrated output data at a ratiometric analog voltage output. The pressure range 15 to 115 kPa is mapped linearly to the nominal output range VAOUT,1 to VAOUT,2. Sensor specific calibration data, configuration and product ID are stored in an embedded NVM.
