SM1111-EEN-S-165-000 Datasheet | Silicon Microstructures

Analog Barometric Air Pressure (BAP) Sensor SM1111-EEN-S-165-000 Barometric Air Pressure (BAP) Sensor Features - Fully integrated and pensated pressure sensor - Measurement of absolute pressure: 60 - 165 k Pa - Full thermal pensation to accuracy ±1.0 %FS - Ratiometric analog output with wide linear range - Two 16-bit ADCs for acquisition of pressure and temperature inputs; pressure acquired at 20 k S/s - High Resolution Digital to analog converter (DAC) - Diagnosis of sensor, sensor supply wiring, and NVM check-sum supervision at power-on - Supply voltage 5.0 V +/- 0.5V - Large operating temperature range -40 to + 85°C - Automotive qualified acc. to AEC-Q100 DESCRIPTION The SM1111-EEN-S-165-000 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 pensation 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 60 to 165 k Pa 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. Silicon Microstructures, Inc. 2001-2019.
