Silicon Microstructures(SMI) SM7391-BCE-S-500-000

The SM7000/SM6000/SM5000 are low pressure MEMS sensors offering state- of- the- art pressure transducer technology and CMOS mixed signal processing technology to produce either an analog and/or digital output fully conditioned, multi- order pressure and temperature compensated. This series provides JEDEC standard SOIC- 16 package with vertical or horizontal porting options. It is available in gage, differential and asymmetric differential configurations. With the 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.
