The SM1X91 series are a medium pressure MEMS sensor family offering state-of-the-art pressure transducer technology and CMOS mixed signal processing technology to produce both digital & analog output, fully conditioned, multi-order pressure and temperature compensated outputs. This series provides two JEDEC standard SOIC-16 packages with dual vertical or horizontal port options. It is available in gauge, differential or asymmetric 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.
Customer-specified pressure ranges and supply voltages are available.
The SM1291, SM1391 and SM1491 series are shipped in sticks or tape & reel.
