SM9543 Ultra Low Differential Pressure Sensor

Not for new designs - please see the SM9333/SM9336 new ultra low digital differential pressure sensors. The SM9543 Series is an ultra low differential pressure 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 package with a dual vertical porting option.  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.  DOWNLOAD LOW PRESSURE
