SM5X21, 6X21 & 7X21 Ultra Low Pressure Sensors With Digital Output

DESCRIPTION

The SM5XXX, SM6XXX, and SM7XXX are digital, low pressure MEMS sensor families offering state of the art pressure transducer technology and a CMOS mixed signal processing technology to produce a digital, fully-conditioned, multi-order pressure and temperature-compensated sensor in JEDEC standard SOIC-16 packaging with dual ports (horizontal or vertical). It is available in compound gauge, symmetrical or asymmetrical differential configurations. With dual porting, a vacuum gauge measurement is possible to minimize altitude errors due to changes in ambient pressure.

 

  • SM5XXX: pressure range of 56 to 140 cmH2O (40 to 102 mmHg)
  • SM6XXX: pressure range of 21 to 56 cmH2O (15 to 41 mmHg)
  • SM7XXX: pressure range of 10 to 20 cmH2O (7.36 to 14.7 mmHg)
