MEMS Ultra-Low Pressure Sensor

MEMS Pressure Sensor
MEMS Pressure Sensor

SMI (Silicon Microstructures, Inc.) introduces the SM9543-005M-D-C-3-S MEMS pressure sensor designed especially for the ultra-low pressure market. The 14-Bit resolution and 1.5% accuracy provide the user high performance while the 0.2% full-scale offset stability per year provides the reliability and long-term reliability for critical care products. Available in low pressure ranges of +/- 5 mbar (+/- 0.07 PSI). The SM9543 stands to revolutionize the next generation of ultra-low pressure products with an I2C digital interface coupled with the highest accuracy and stability in the industry.

At the heart of the SM9543 is the MEMS pressure transducer with SMI’s novel and proprietary silicon technology platform. With SMI’s technology, the user can attain the highest level of accuracy with long-term high performance as demanded of the stringent medical industry. Mating with the MEMS pressure sensor is a state-of-the-art signal-conditioning IC providing full pressure calibration and temperature compensation with a user-friendly I2C digital interface. The pressure sensor housing is based on standard surface mount technology standards and features a JEDEC compliant SOIC-16 footprint for straight-forward PCB design and assembly. Design engineers will appreciate the design flexibility and repeatability of the SM9543. Fully qualified and in production, the SM9543 is ready for design-in and user qualification.
