Low Pressure Digital & Analog Sensor (SM5X91)

The SM5291, SM5391 & SM5491 Series are a low pressure MEMS sensor family offering state-of-the-art pressure transducer technology and CMOS mixed signal processing technology to produce a digital & analog output, fully conditioned, multi-order pressure and temperature compensated sensor in JEDEC standard SOIC-16 package with a dual vertical or horizontal ports. It is available in gauge, differential, asymmetric differential configurations. With dual porting, a reference measurement is possible to minimize 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 custom correction algorithm.
