The SM4000/SM1000 are medium 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 provide a JEDEC standard SOIC-16 package with vertical or horizontal porting options or a JEDEC SOIC-10 package with a vertical port. 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.
Customer-specified pressure ranges and supply voltages are available.
The SM4000/SM1000 are shipped in sticks or tape & reel.
The SM4000 and SM1000 digital output only sensors earned the AccuStable quality label. The AccuStable brand stands for <1% total error band initially and <1% shift during operation over 10 year lifetime. Qualification is based on 1000 hours HTOL (High-temperature operating life) test at 85°C with 5V.
