Respiratory Low Pressure Sensor SM5882

sm9541
SM9541
DESCRIPTION

The SM9541 Series is a digital, low pressure MEMS sensor family offering state-of-the-art pressure transducer technology and CMOS mixed signal processing technology to produce a digital, fully conditioned, multi-order pressure and temperature compensated sensor in JEDEC standard SOIC-16 with a dual vertical porting option. It is available in both compound gauge or differential pressure configurations. With the dual porting, a vacuum-gauge measurement is possible to minimize altitude errors due to changes in ambient pressure.

Combining the pressure sensor with a signal-conditioning ASIC in a single package simplifies the use of advanced silicon micro-machined pressure sensors. The pressure sensor can be mounted directly on a standard printed circuit board and a high level, calibrated pressure signal can be acquired from the digital interface. This eliminates the need for additional circuitry, such as a compensation network or microcontroller containing a customer correction algorithm.

SM9541 pressure ranges:
-1..20cmH2O (-1...20mbar)
-0.5..10cmH2O (-0.5...10mbar)
-5..40cmH2O (-5...40mbar)
-5..100cmH2O (-5...100mbar)
