Low Pressure Digital Sensor (SM4X31)

The SM4X31 Series is a low pressure MEMS sensor family offering state-of-the-art pressure transducer technology and CMOS mixed signal processing technology to produce a 16-bit Digital output, fully conditioned, multi-order pressure and temperature compensated outputs. All SM4X31 sensors provide a 1%FS digital output accuracy. This series provides JEDEC standard SOIC-16 package with a dual vertical or horizontal ports  options. With the dual porting, a reference measurement is possible to minimize errors due to changes in ambient pressure. For a smaller footprint we offer the JEDEC SOIC-10 package option with one port. The SM4X31 Series is available in gauge, differential and asymmetric differential configurations.


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 custom correction algorithm.

Customer-specified   pressure   ranges   and   supply   voltages    are available.
The SM4231, SM4331 and SM4431 series are shipped in sticks or tape & reel.
