SM1111-EEN-S-115-001
Overview
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.
- Fully integrated and compensated pressure sensor
- Measurement of absolute pressure: 15 - 115 kPa
- Full thermal compensation 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 kS/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
